The mirror fold driver is handled by the DRV8873-Q1, a 10-A integrated motor driver. This driver can provide the 8-A maximum peak current needed to drive the mirror fold motor.

Figure 2-8 shows the configuration schematic. The capacitors (C6, C7, C8, and C9) are selected based on the recommendations on the DRV8873-Q1 data sheet. Likewise, the data sheet recommends a pullup resistor greater than 10 kΩ on the nFAULT pin. The two IPROPI resistors are chosen such that the maximum drive current is set to 8 A which is the maximum current rating of the motor. The SRC pins are shorted to GND to create a low impedance path between the power FET source and GND.
