DRV8231/A 33 V H-Bridge Motor Drivers from Texas Instruments
Texas Instruments’ DRV8231 and DRV8231A are integrated motor drivers with an N-channel H-bridge, charge pump, current regulation, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half-bridges and 100% duty-cycle driving. The DRV8231/A implements a current regulation feature by comparing the analog input VREF and the voltage across a current-sense shunt resistor on the ISEN pin. The ability to limit current can significantly reduce large currents during motor startup and stall conditions.
