3 Description

The DRV8410 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 low-battery

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 regulation by

comparing an internal refernce voltage to the voltage

on the xISEN pins, which is proportional to motor

current through an external sense resistor. 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

undervoltage, overcurrent, and overtemperature.

The DRV8410 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.
