7.1 Overview
The DRV8801A-Q1 device is an integrated motor driver solutions for brushed-DC motors. The device integrates
a DMOS H-bridge and current sense and protection circuitry. The device can be powered with a supply voltage
between 6.5 V and 36 V, and is capable of providing an output current up to 2.8-A peak.
A simple PHASE and ENABLE interface allows control of the motor speed and direction.
A shunt amplifier output is provided for accurate current measurements by the system controller. The VPROPI
pin outputs a voltage that is five-times the voltage seen at the SENSE pin.
A low-power sleep mode is included which allows the system to save power when not driving the motor.
