DRV8821DCAR Description

Short technical summary and product information.

The DRV8821DCAR from Texas Instruments is a dual microstepping-capable stepper motor controller and driver solution. It is designed for applications such as printers, scanners, and other office automation equipment.

 

This device features two independent stepper motor driver circuits, each containing H-bridge drivers and microstepping indexer logic. The driver blocks utilize N-channel power MOSFETs configured as an H-bridge to drive the motor windings. A simple step/direction interface facilitates easy integration with controller circuits.

 

Key electrical specifications include an operating supply voltage range of 8V to 32V and a peak output current of 1.5A per winding. The DRV8821DCAR supports microstepping levels of 1, 1/2, 1/4, and 1/8, allowing for precise motor control. It also offers selectable slow or mixed decay modes for current regulation.

 

The DRV8821DCAR is housed in a 48-HTSSOP package with an exposed pad, suitable for surface mounting. The operating temperature range is -40°C to 150°C (TJ). The device includes built-in protection against undervoltage, overtemperature, and overcurrent conditions.
