DRV8821 双路步进电机控制器/驱动器

DRV8821 描述

The DRV8821 provides a dual microstepping-capable stepper motor controller/driver solution for printers, scanners, and other office automation equipment applications. Two independent stepper motor driver circuits include four H-bridge drivers and microstepping-capable indexer logic. Each of the motor driver blocks employ N-channel power MOSFETs configured as an H-bridge to drive the motor windings. A simple step/direction interface allows easy interfacing to controller circuits. Pins allow configuration of the motor in full-step, half-step, quarter-step, or eighth step modes, and the selection of slow or mixed decay modes. Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature
