DRV8328xEVM User's Guide
This document is provided with the
DRV8328x data sheet (DRV8328 4.5-V to 60-V Three-Phase Smart Gate
implementation of the EVM and shows how to set up and power the board.
The DRV8328AEVM comes automatically populated with and configured for the DRV8328A. It is also
compatible for the DRV8328B, DRV8328C, and DRV8328D variants (see
3.4.2), but the user will need to modify the board to make it compatible for each variant (see
and
Table
3-4).

User-adjustable jumpers, resistors, and switches on DRV8328AEVM 3.4.1 DRV8328A/B Compatibility The DRV8328AEVM default is the DRV8328A (Hardware variant), but can also be compatible with the DRV8328B. The main difference is that DRV8328A operates in 6x PWM mode and DRV8328B operates in 3x PWM mode. Figure 3-7 shows the default resistors to select the A/B variant when the DRV8328A or DRV8328B is used.

1. Enter the PWM frequency in Hz using the “PWM Frequency (Hz)” text box. Press Enter. 2. Adjust the MCU dead time and Acceleration Delay values. For DRV8328A/B, it is recommended to use the DT potentiometer and set MCU dead time to 0 ns. - Page 18 • MCU Dead Time – Sets the MCU dead time to the PWM inputs in ns. Recommended to set DT to the minimum on the DRV8328A/B by setting placing 0-ohm resistor for R91. • Duty Cycle – Sets the duty cycle of the motor when potentiometer is disabled.
