Description for the DRV8428E

The DRV8428E/P devices are dual H-bridge motor drivers for a widevariety of industrial applications. The devices can be used for driving two DC motors, or a bipolarstepper motor. The output stage of the driver consists of N-channel power MOSFETs configured as twofull H-bridges, current sensing and regulation, and protection circuitry. The integrated currentsensing uses an internal current mirror architecture, removing the need for a large power shuntresistor, saving board area and reducing system cost. A low-power sleep mode is provided to achieveultra- low quiescent current draw by shutting down most of the internal circuitry. Internalprotection features are provided for supply undervoltage lockout (UVLO), output overcurrent (OCP),and device overtemperature (TSD). The DRV8428E/P is capable of driving up to 1-A full scale or0.7-A rms output current per H-bridge (dependent on PCB design).
