Meiyuxin Technology Supply Original Spot DRV8251DDAR 50V, 4.1A H-Bridge Motor Driver with Integrated Current Regulation and Latching OCP Quality Assurance Brand New Original! ! !

Meiyuxin Technology only recycles regular channel sources, such as agents, traders, terminal factories, etc., and does not accept non-regular channel sources.

Product Details

The DRV8251 device 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 of the internal circuitry. Internal protection features include supply undervoltage lockout, output overcurrent, and device overtemperature.
