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 25°C).
A simple step/direction interface allows easy
interfacing to controller circuits. Terminals allow
configuration of the motor in full-step up to 1/32-step
modes. Decay mode is programmable.
Internal shutdown functions are provided for
overcurrent protection, short circuit protection,
undervoltage lockout and overtemperature.
The DRV8824-Q1 is available in a 28-terminal
HTSSOP package with PowerPAD™ (Eco-friendly:
RoHS & no Sb/Br).
