3 Description

The DRV8411A is a dual H-bridge motor driver that

can drive one or two DC brush motors, one stepper

motor, solenoids, or other inductive loads. The tripler

charge pump allows the device to operate down to

1.65 V to accommodate 1.8-V supply rails and lowbattery

conditions. The charge pump integrates all

capacitors and allows for 100 duty cycle operation.

The inputs and outputs can be paralleled to drive high

current brush DC motors with half the RDS(ON).

The device implements current sensing and

regulation. Internal current mirrors output the current

sense information on the IPROPI pins, eliminating the

need for large power shunt resistors, thereby saving

board area and reducing system cost. The IPROPI

outputs allow a microcontroller to detect motor stall

or changes in load conditions. Using the VREF pin,

the devices can regulate the motor current during

startup and high-load 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

undervoltage, overcurrent, and overtemperature.

The DRV8411A is part of a family of devices

which come in pin-to-pin, scalable RDS(ON) options to

support various loads with minimal design changes.

family. View our full portfolio of brushed motor drivers
