Texas Instruments DRV8251 4.1A Brushed DC Motor Driver is an integrated motor driver with 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 DRV8251 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.
A low-power sleep mode achieves ultra-low quiescent current draw by shutting down most internal circuitry. Internal protection features include supply undervoltage lockout, output overcurrent, and device overtemperature. The Texas Instruments DRV8251 is part of a family of devices that comes in pin-to-pin, scalable RDS(on), and supply voltage options to support various loads and supply rails with minimal design changes.
