The DRV8821DCA from Texas Instruments is a dual microstepping-capable stepper motor controller and driver solution designed for applications like printers and scanners. It features two independent stepper motor driver circuits, each with four H-bridge drivers and microstepping indexer logic.
The device supports a wide operating supply voltage range of 8V to 32V and can deliver a peak output current of 1.5A per winding. It offers flexible microstepping capabilities, allowing for resolutions of 1, 1/2, 1/4, or 1/8 steps. The control interface is a simple step/direction (STEP/DIR) hardware interface, making integration straightforward.
Key electrical specifications include a full-scale current of 1.5A, low RDS(ON) of 550mΩ (HS + LS), and a low sleep current of 20µA. The DRV8821DCA is housed in a thermally-enhanced 48-HTSSOP surface mount package. It includes built-in protection against undervoltage, overtemperature, and overcurrent conditions.
