Description

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, undervoltage lockout, and overtemperature.

The DRV8821 is packaged in a 48-pin HTSSOP package (Eco-friendly : RoHS & no Sb/Br).
