نظرة عامة على المنتج
The DRV8843PWPR from Texas Instruments is a dual H-bridge motor driver in a 28-pin HTSSOP PowerPAD package. With 2.5A per bridge output current, 11V maximum supply, and integrated MOSFETs with 360mOhm Rds(on), it drives two DC motors or one stepper motor with built-in current regulation and fault protection.
