Overview
The DRV8849 is a dual stepper motor driver for industrial and consumer applications. The device is fully integrated with four N-channel power MOSFET H-bridge drivers, one microstepping indexer for each stepper, and integrated current sensing. The DRV8849 is capable of driving up to 1.5-A full-scale output current (dependent on PCB design). The DRV8849 uses an internal current sense architecture to eliminate the need for four external power sense resistors, saving PCB area and system cost. The device uses an internal PWM current regulation scheme with smart tune decay mode. Smart tune automatically adjusts for desired current regulation, compensates for motor variation and aging effects and reduces audible noise and vibration from the motor. Simple STEP/DIR interfaces allow an external controller to manage the direction and step rate of the stepper motors. The device can be configured in full-step to 1/256 microstepping. A low-power sleep mode is provided using a dedicated nSLEEP pin. Protection features are provided for supply undervoltage, charge pump faults, overcurrent, short circuits, and overtemperature. Fault conditions are indicated by one nFAULT pin for each stepper.
