The DRV8821DCAR is a dual bipolar stepper motor driver capable of delivering up to 1.5A per winding. It features built-in microstepping indexers that support up to 1/8 microstepping, allowing for smooth motor control. The device operates within a supply voltage range of 8V to 32V and includes a simple step/direction interface for easy integration with controller circuits. The driver incorporates N-channel power MOSFETs configured as H-bridges for efficient motor winding control. It offers three-bit winding current control, enabling up to eight current levels, and provides selectable decay modes, including slow and mixed decay. The DRV8821DCAR is designed with built-in protection features against undervoltage, overtemperature, and overcurrent conditions, ensuring reliable operation in various applications such as printers, scanners, and robotics. Packaged in a 48-pin HTSSOP format, the device is suitable for applications requiring compact and thermally efficient solutions. The operating temperature range is specified from -40¬8C to 85¬8C, making it versatile for different environmental conditions.
