2.8 MCx Variant Configuration

To use the DRV8376EVM using the MCx variant IC, use the tables and figure below to configure the device correctly. Make sure the resistors for SPI variant are unpopulated or DNP, that R17, R18, and R19 are populated with 0 ohm resistors or shorted, and R20 is populated with a 5.1k ohm resistor.

The MCx variant of the DRV8376 IC utilizes the Hardware variant resistors for configuration of MODE, GAIN_SLEW_tLOCK, DIR, and ADVANCE.
