1. Describe
The DRV8812RHDT provides an integrated motor driver Printers, Scanners and Other Automation Solutions device application. The device has two H-bridges driver, and can drive one or two bipolar stepper motors DC. Each output driver block includes N-channel power MOSFETs are configured as full H- bridge to drive the motor windings. DRV8812RHDT is Capable of driving up to 1.6A of output current (with proper heat dissipation, at 24 V and 25°C). A simple parallel digital control interface is compatible with industry standard equipment. The decay mode is programmable. An internal shutdown function provides over current protection, short circuit protection, down voltage lock-up and overheating. DRV8812RHDT in 28-pin HTSSOP Available in PowerPAD™ Package, 28-Pin QFN Packaged PowerPAD™ (Environmental: RoHS and Sb/Br Free).
