SLVSCH0 – APRIL 2014 DRV8824-Q1 Automotive Motor Controller IC
1 Features 3 Description The DRV8824-Q1 provides an integrated motor driver
solution for automotive applications. The device has
two H-bridge drivers and a microstepping indexer,
and is intended to drive a bipolar stepper motor. The
output driver block for each consists of N-channel
power MOSFET’s configured as full H-bridges to
drive the motor windings. The DRV8824-Q1 is
capable of driving up to 1.6-A of output current (with
proper heatsinking, at 24 V and 25В°C). 1 Qualified for Automotive Applications
