Introduction

AI Translation

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 can drive up to 1.1A RMS current (depending on PCB design).

The DRV8436 uses an internal current sensing architecture, eliminating the need for two external power sense resistors, thereby reducing PCB area and system cost. The device uses an internal PWM current regulation scheme that can select between smart tune, slow, and mixed decay options. Smart tune decay technology automatically adjusts to achieve excellent current regulation performance and compensate for motor variations and aging effects.

With a simple STEP/DIR interface, the direction and step rate of the stepper motor can be managed by an external controller. A dedicated nSLEEP pin provides a low-power sleep mode for ultra-low quiescent standby current. Protection features include: supply undervoltage, charge pump fault, overcurrent, short circuit, and overtemperature protection. Fault conditions are indicated via the nFAULT pin.
