Test Points
Every pin on the DRV88xx device has been brought out to a test point, and labels on the silkscreen
identify 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 is
provided with corresponding function name on its particular column.

Connectors
Power Connectors
The DRV88xx Customer EVM offers access to VM (Motor Voltage) power rail via a terminal block (J6) and
header pins (J7). A set of test clips at the top of the board in parallel with the terminal block allows for the
monitoring 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 datasheet
recommended parameters.

Control Signals
The header J12 brings out all the control signals of the IC. For the pins that have multiple functionality
depending on the IC used, the various functions are labeled in a table. The correct functionality can be
ascertained from this table in the column corresponding to the IC being used. While the signals are being
driven using the on-board MCU, these pins can be used to monitor the signals. However, the user can
also apply external signals using this header. In such a case, the on-board MCU should be powered off by
de-populating the MCU_PWR jumper. This will ensure that the there is no conflict between the signals
applied externally and the signals being forced by the on-board MCU. If only a few signals are being
driven externally and the user wants to retain the on-board MCU for the remaining signals, the
corresponding resistors R12-R18 can be de-soldered to ensure that there is no conflict.
1.3
Jumpers/Resistors
nFault – If a jumper is applied at nFault (JP5), the LED (D4) will light in the case of a fault. Even if the
jumper is not applied, the voltage of the nFault can be monitored across the two pin headers (JP5 or
JP12).
LDO Supply – There is an LDO (TPS7A4001DGNT) on board that can regulate the VM voltage down to
3.3V. This voltage (VDD) is used to power the on board MCU (MSP430F2617) and is also used as the
pull-up for the nFault pin. This voltage is used to light up the nFault LED. If a jumper is not applied to LDO
supply (JP6), the onboard MCU is no longer powered. If a jumper is not applied, the user must drive the
part using an external MCU by applying signals to the signal headers (J12), and the user must apply a
VDD to implement the nFault LED function. If a jumper is applied the onboard MCU is powered on and
can 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 the
jumper is not applied, the user must implement an MCU or apply signals to the signal headers (J12). If the
jumper is not applied nFault still receives VDD (3.3 V). If jumper at (JP4) is applied, MCU-RST works as a
manual reset button for the MCU.
NOTE: Both JP4 and JP6 must be populated to enable the on board MCU and use the
DRV8803/04/05 EVM software.
Resistors – R8, R9, R10, R11 are resistors used to identify which device is being implemented on the
EVM (DRV8803, 04, 05 or 06). The MCU powers up based on these resistors. However, the GUI can be
used 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.

Motor Outputs
There are two ways of connecting a bipolar stepper motor into the EVM: five pin header (J8), and five
position 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 are
Kelvin connections and are not rated for high current output. All pins are labeled on the silk-screen for
clarity.

DRV880x GPIO Control Signals
Once the application is communicating with the interface board, the control signals can be actuated by
clicking on pins to send each control hi (green), lo (red), or in special cases open (orange). Each tab will
have 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 the
respective control signal, a red pin translates to a LO level on the respective control signals, and in special
cases, 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 to
Reset Button (See motor control).
INx – Control appears on the DRV8803 device. Toggling HI (green) sets PWM of input X to a duty cycle of
100%. Toggling LO (red) sets PWM of input X to a duty cycle of 0%. Automatically toggles in
correspondence to INx sliders and % duty cycle combo boxes (See PWM control). The pin will show
orange if the user selects anything other than a 0% of 100% duty cycle. If user clicks pin to toggle from
orange the pin will go LO (red).
STEP – Control appears on the DRV8805 device. Toggling LO (red) and then HI (green) will enable a
bipolar stepper motor to step once. Toggles in correspondence to Pulse 1 Step button (See speed
control).
DIR – Control appears on the DRV8805 device. Toggling HI (green) will allow the motor to operate in the
forward 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 is
operating in (microstepping – full, half, wave mode, reverse). The following look up table shows the
combinations and their results:

PWM Control
Figure 16. DRV8803 PWM Control
The DRV8803 can be utilized to control DC motors. For the purpose to control DC motor speed, a slider is
provided which applies a PWM to each respective input. The PWM slider consists of an 8 bit number so
positions from 0 to 255 are obtained. The MSP430 directly transforms this 8 bit number into the respective
duty cycle. PWM frequency is around 31.25 KHz.
When the slider bar is moved across, the Duty Cycle indicator is updated accordingly. When the duty
cycle is set from the selector, the slide bar is updated accordingly. The resulting duty cycle is an integer
number 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% the
corresponding 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).

Motor Control
The Windows Application, in conjunction with the MSP430F2617 microcontroller, utilizes a series of timers
to 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 that
accelerating and decelerating profiles are achieved. Both acceleration and deceleration are controlled by
the same parameters Acceleration Rate and Time Base.
When the motor starts, the controller will accelerate the motor in order to reach the Pulses Per Second
speed. Acceleration Rate is an 8 bit number (0 to 255) that gets added to the current Pulses Per Second
speed and Time Base is an 8 bit number (0 to 255) that specifies how many milliseconds will elapse from
one speed increase to the next. Once the specified Pulses Per Second has been achieved, the
acceleration stops.

Stepper PWM Slide Bar – Appears on the DRV8803 and DRV8804. On the DRV8803 this sets all of the
INx PWM slide bars to whatever the Stepper PWM slide bar is set to. This controls the PWM rate of the
stepper. On the DRV8804, the stepper PWM controls the PWM rate of the stepper and calculates the
corresponding duty cycle which updates automatically as the slider is moved. If the user sets the % duty
cycle, the position of the slider is updated automatically.
Enable Motor Button – Appears on all three devices. This enables the motor and automatically toggles
the corresponding pin (see DRV88xx GPIO signals).
Reset Button – Appears on all three devices. This automatically sends the reset pin either HI (green) then
LO (red) or LO (red) then HI (green) effectively resetting your device. (Reset pin must be LO for motor to
operate – see DRV88xx GPIO signals).
Motor Direction Radio Buttons – Appears on all three devices. Always defaults to reverse direction on
default. Determines whether the motor is operating in forward or reverse direction. Automatically toggles
corresponding 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 and
automatically toggles the corresponding SMx pin (see DRV88xx GPIO signals).

3.11 Diagnostic Output
The DRV8806 will return data on every SPI transaction. This data contains valuable information as to
whether each output was subjected to a fault or not. If a fault was present, the logic state is the SPI data
packet 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 must
refer to the device’s datasheet for more details on how the fault scheme operates.
3.12 Controlling the EVM Using External Signals
If the user wishes to run the IC using their own external signals/MCU, this can be achieved easily. The
only thing the user needs to do is powered down the MCU using the jumper JP4 labeled MCU_PWR on
the EVM. This removes the power to the MCU and allows the user to control the input signals using the
header J12. The silkscreen can be used to identify the various signals. The resistors R12-18 are meant to
protect the MCU from 5V signals (if applied) to the input pins. The user can de-solder them for better
performance. Please note that once these resistors are de-soldered, the user cannot use the on-board
MCU.

Evaluation Board/Kit Important Notice
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. Persons handling the product(s) must have
electronics training and observe good engineering practice standards. As such, the goods being provided are not intended to be complete
in terms of required design-, marketing-, and/or manufacturing-related protective considerations, including product safety and environmental
measures typically found in end products that incorporate such semiconductor components or circuit boards. This evaluation board/kit does
not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances (RoHS), recycling
(WEEE), FCC, CE or UL, and therefore may not meet the technical requirements of these directives or other related directives.
Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30 days from
the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY SELLER TO BUYER
AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all claims
arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to take any and all
appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY
INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or
services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the product. This
notice contains important safety information about temperatures and voltages. For additional information on TI’s environmental and/or
safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio
frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are
designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may
be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of -0.3 V to 65 V and the output voltage range of -0.3 V to 65 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions
concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.
Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 85°C. The EVM is designed to operate
properly with certain components above 85°C as long as the input and output ranges are maintained. These components include but are
not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified
using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,
please be aware that these devices may be very warm to the touch.
