This document is provided as a supplement to the DRV8803/DRV8804/DRV8805/DRV8806 datasheets. Itdetails the hardware implementation of the DRV8803/04/05/06 EVM Customer Evaluation Module (EVM).

Test Points

PCB www.ti.com




2.1 Test PointsEvery pin on the DRV88xx device has been brought out to a test point, and labels on the silkscreenidentify each signal. These are Kelvin connections and are not meant to be used to drive high currents.These can be used as a sense line.

For those pins that change functionality depending on the respective device being used, a table isprovided with corresponding function name on its particular column.

Figure 2. Test Points

http://www.ti.com


J6

J12

www.ti.com PCB




2.2 Connectors

2.2.1 Power ConnectorsThe DRV88xx Customer EVM offers access to VM (Motor Voltage) power rail via a terminal block (J6) andheader pins (J7). A set of test clips at the top of the board in parallel with the terminal block allows for themonitoring of the input power rail. The polarity of the terminal connections are mentioned in the silkscreen.User must power the EVM using the correct polarity. User must apply VM according to datasheetrecommended parameters.

Figure 3. Power Connectors

http://www.ti.com


PCB www.ti.com




2.2.2 Control SignalsThe header J12 brings out all the control signals of the IC. For the pins that have multiple functionalitydepending on the IC used, the various functions are labeled in a table. The correct functionality can beascertained from this table in the column corresponding to the IC being used. While the signals are beingdriven using the on-board MCU, these pins can be used to monitor the signals. However, the user canalso apply external signals using this header. In such a case, the on-board MCU should be powered off byde-populating the MCU_PWR jumper. This will ensure that the there is no conflict between the signalsapplied externally and the signals being forced by the on-board MCU. If only a few signals are beingdriven externally and the user wants to retain the on-board MCU for the remaining signals, thecorresponding resistors R12-R18 can be de-soldered to ensure that there is no conflict.

2.3 Jumpers/ResistorsnFault – If a jumper is applied at nFault (JP5), the LED (D4) will light in the case of a fault. Even if thejumper is not applied, the voltage of the nFault can be monitored across the two pin headers (JP5 orJP12).

LDO Supply – There is an LDO (TPS7A4001DGNT) on board that can regulate the VM voltage down to3.3 V. This voltage (VDD) is used to power the on board MCU (MSP430F2617) and is also used as thepull-up for the nFault pin. This voltage is used to light up the nFault LED. If a jumper is not applied to LDOsupply (JP6), the onboard MCU is no longer powered. If a jumper is not applied, the user must drive thepart using an external MCU by applying signals to the signal headers (J12), and the user must apply aVDD to implement the nFault LED function. If a jumper is applied the onboard MCU is powered on andcan be used to drive the part.

NOTE: If the user is applying an external VDD, please ensure that the jumpers JP6 (LDO Supply)and JP4 (MCU_PWR) are de-populated.

MCU_PWR - Applying a jumper at MCU PWR (JP4) enables the MSP430 and logic on the EVM. If thejumper is not applied, the user must implement an MCU or apply signals to the signal headers (J12). If thejumper is not applied nFault still receives VDD (3.3 V). If jumper at (JP4) is applied, MCU-RST works as amanual reset button for the MCU.

NOTE: Both JP4 and JP6 must be populated to enable the on board MCU and use theDRV8803/04/05 EVM software.

Resistors – R8, R9, R10, R11 are resistors used to identify which device is being implemented on theEVM (DRV8803, 04, 05 or 06). The MCU powers up based on these resistors. However, the GUI can beused to select the device on the EVM too. If the user changes the DRV8803 to another flavor of the IC(namely DRV8804/05/06) the appropriate tab in the GUI should be selected and ‘CONFIGURE DEVICE’should be selected.

Figure 4. Jumpers/Resistors

2.4 Motor OutputsThere are two ways of connecting a bipolar stepper motor into the EVM: five pin header (J8), and fiveposition terminal block (J9). The optimal way to connect a DC motor is the two pin headers (J1/J2/J3/J4).Although feasible, we do not recommend the connection of any motor into the test clips as these areKelvin connections and are not rated for high current output. All pins are labeled on the silk-screen forclarity.

4.6 DRV880x GPIO Control SignalsOnce the application is communicating with the interface board, the control signals can be actuated byclicking on pins to send each control hi (green), lo (red), or in special cases open (orange). Each tab willhave a different set of control signals depending on the device being interfaced with.

Functionality of control signals is identical across the platform. A green pin translates to a HI level on therespective control signal, a red pin translates to a LO level on the respective control signals, and in specialcases, an orange pin translates to an open signal, and a gray pin translates to a non-control pin.

nENBL – Control appears on all three devices. Toggling it LO (red) enables the chip, and toggling it HI(green) disables the chip. Automatically toggles in correspondence to the Enable Button on all three chips(See motor control).

Reset – Control appears on all three devices. Must be toggled LO (red) in order for the device to operate.If toggled HI (green) and then LO (red) it resets the chip. Automatically toggles in correspondence toReset Button (See motor control).

INx – Control appears on the DRV8803 device. Toggling HI (green) sets PWM of input X to a duty cycle of100%. Toggling LO (red) sets PWM of input X to a duty cycle of 0%. Automatically toggles incorrespondence to INx sliders and % duty cycle combo boxes (See PWM control). The pin will showorange if the user selects anything other than a 0% of 100% duty cycle. If user clicks pin to toggle fromorange the pin will go LO (red).

STEP – Control appears on the DRV8805 device. Toggling LO (red) and then HI (green) will enable abipolar stepper motor to step once. Toggles in correspondence to Pulse 1 Step button (See speedcontrol).

DIR – Control appears on the DRV8805 device. Toggling HI (green) will allow the motor to operate in theforward direction, while toggling LO (red) will allow the motor to operate in the reverse direction.Automatically toggles in correspondence to Motor Direction radio buttons (See Motor Control)

SMx – Control appears on the DRV8805 device. Toggling these pins selects the mode that the motor isoperating in (microstepping – full, half, wave mode, reverse). The following look up table shows thecombinations and their results:

Figure 35. SMx

Automatically toggles in correspondence to microstepping radio buttons (see motor control).

4.7 PWM Control

Figure 36. DRV8803 PWM Control

The DRV8803 can be utilized to control DC motors. For the purpose to control DC motor speed, a slider isprovided which applies a PWM to each respective input. The PWM slider consists of an 8 bit number sopositions from 0 to 255 are obtained. The MSP430 directly transforms this 8 bit number into the respectiveduty cycle. PWM frequency is around 31.25 KHz.

When the slider bar is moved across, the Duty Cycle indicator is updated accordingly. When the dutycycle is set from the selector, the slide bar is updated accordingly. The resulting duty cycle is an integernumber between 0 and 100 and it is computed according to the equation:%Duty Cycle = PWM / 255 x 100 (1)

Each corresponding pin on the chip indicator is toggled automatically. If the duty cycle is 0% thecorresponding chip is toggled to LO (red). If the duty cycle is 100% the corresponding pin is toggled to HI(green). If the duty cycle is set to anything besides 100% or 0% the corresponding pin is toggled (orange).

Pulses Per Second





4.8 Motor ControlThe Windows Application, in conjunction with the MSP430F2617 microcontroller, utilizes a series of timersto coordinate the rate of steps sent to the device. Once all the control signals are configured accordingly,the motor is ready to be turned.

The DRV8803/04/05 Customer EVM allows for the possibility of coordinating step rates such thataccelerating and decelerating profiles are achieved. Both acceleration and deceleration are controlled bythe same parameters Acceleration Rate and Time Base.

When the motor starts, the controller will accelerate the motor in order to reach the Pulses Per Secondspeed. Acceleration Rate is an 8 bit number (0 to 255) that gets added to the current Pulses Per Secondspeed and Time Base is an 8 bit number (0 to 255) that specifies how many milliseconds will elapse fromone speed increase to the next. Once the specified Pulses Per Second has been achieved, theacceleration stops.

Figure 38. DRV88003/04/05 Motor Control Windows

Stepper PWM Slide Bar – Appears on the DRV8803 and DRV8804. On the DRV8803 this sets all of theINx PWM slide bars to whatever the Stepper PWM slide bar is set to. This controls the PWM rate of thestepper. On the DRV8804, the stepper PWM controls the PWM rate of the stepper and calculates thecorresponding duty cycle which updates automatically as the slider is moved. If the user sets the % dutycycle, the position of the slider is updated automatically.

Enable Motor Button – Appears on all three devices. This enables the motor and automatically togglesthe corresponding pin (see DRV88xx GPIO signals).

Reset Button – Appears on all three devices. This automatically sends the reset pin either HI (green) thenLO (red) or LO (red) then HI (green) effectively resetting your device. (Reset pin must be LO for motor tooperate – see DRV88xx GPIO signals).

Motor Direction Radio Buttons – Appears on all three devices. Always defaults to reverse direction ondefault. Determines whether the motor is operating in forward or reverse direction. Automatically togglescorresponding direction pin in the case of the DRV8805 (see DRV88xx GPIO signals).

Microstepping – Appears on the DRV8805. Determines the mode that the motor is operating in andautomatically toggles the corresponding SMx pin (see DRV88xx GPIO signals).

4.9 Speed Control

Figure 39. DRV88003/04/05 Speed Control Windows

Speed Control/Start Steps - The speed is set by either using the slide control, or selecting the Steps perSecond value in the Steps Per Second number box. Using either control the other will be updatedautomatically. Pressing the “Start Steps” button, will start the timer and the motor will step at the ratespecified by the Steps Per Second number Box/Slider. Once the “Start Steps” button is pressed itbecomes the “Stepping (Pause Steps)” button. Press the “Stepping (Pause Steps)” button to stop thestepper motion. The Steps Per Second rate is updated automatically anytime the slider of the number boxis used.

Pulse 1 Step – Control only applies to the DRV8805. Clicking this button will step the motor once, andalso toggle the corresponding STEP pin HI (green) then LO (red) or LO (red) then HI (green) (seeDRV88xx GPIO signals). A step takes place when the pin goes from LO (red) to HI (green)

Acceleration profile automatically updates when either slide bar or number box is changed.

4.11 Diagnostic OutputThe DRV8806 will return data on every SPI transaction. This data contains valuable information as towhether each output was subjected to a fault or not. If a fault was present, the logic state is the SPI datapacket is HI (green), whereas no fault present are represented by LO (red).

Faults generated on a per output basis could be caused by an open load or by over current. User mustrefer to the device’s datasheet for more details on how the fault scheme operates.

4.12 Controlling the EVM Using External SignalsIf the user wishes to run the IC using their own external signals/MCU, this can be achieved easily. Theonly thing the user needs to do is powered down the MCU using the jumper JP4 labeled MCU_PWR onthe EVM. This removes the power to the MCU and allows the user to control the input signals using theheader J12. The silkscreen can be used to identify the various signals. The resistors R12-18 are meant toprotect the MCU from 5V signals (if applied) to the input pins. The user can de-solder them for betterperformance. Please note that once these resistors are de-soldered, the user cannot use the on-boardMCU.
