DRV8824-Q1 Datasheet PDF - TI

●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).
