The DRV8436 is a stepper motor driver for industrial and consumer end equipment applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8436 is capable of driving up to 1.1-A rms (dependent on PCB design).

The DRV8436 uses an internal current sense architecture to eliminate the need for two external power sense resistors, saving PCB area and system cost. The device uses an internal PWM current regulation scheme selectable between smart tune, slow and mixed decay options. Smart tune decay technology automatically adjusts for optimal current regulation performance and compensates for motor variation and aging effects.

A simple STEP/DIR interface allows an external controller to manage the direction and step rate of the stepper motor. A low-power sleep mode is provided for very low standby quiescent standby current 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 the nFAULT pin.
