The DRV8899-Q1 is a stepper motor driver for automotive applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8899-Q1 is capable of driving up to 1-A full scale or 0.7-A rms output current (13.5-V and TA = 25°C, dependent on PCB design).
