Introduction

AI Translation

DRV8424/25 is a stepper motor driver for industrial and consumer applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8424 can drive a full-scale output current up to 2.5A; the DRV8425 can drive a full-scale output current up to 2A (depending on PCB design). The DRV8424/25 uses an internal current sensing architecture that eliminates the need for two external power sense resistors, reducing PCB area and system cost. These devices use an internal PWM current regulation scheme with selectable smart tune, fast, slow, and mixed decay options. Smart tune delivers excellent current regulation performance through automatic adjustment, compensating for motor variation and aging effects while reducing audible motor noise. With a simple STEP/DIR interface, the direction and step rate of a stepper motor can be managed by an external controller. The device is configurable in multiple step modes, from full-step to 1/256 microstepping. The device provides a low-power sleep mode via a dedicated nSLEEP pin. Protection features include: supply undervoltage, charge pump fault, overcurrent, short circuit, and overtemperature protection. Fault conditions are indicated via the nFAULT pin.
