Description

The DRV8251A device is an integrated motor driver

with N-channel H-bridge, charge pump, current sense

feedback, current regulation, and protection circuitry.

The charge pump improves efficiency by supporting

N-channel MOSFET half bridges and 100% duty cycle

driving.

An internal current mirror architecture on the IPROPI

pin implements current sensing and regulation. This

eliminates the need for a large power shunt resistor,

saving board area and reducing system cost. The

IPROPI current-sense output allows a microcontroller

to detect motor stall or changes in load conditions.

The external voltage reference pin, VREF, determines

the threshold of current regulation during start-up and

stall events without interaction from a microcontroller.

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.

The DRV8251A is part of a family of devices which

come in pin-to-pin, scalable RDS(on) and supply

voltage options to support various loads and supply

rails with minimal design changes. See Section 5 for

information on the devices in this family. View the full
