3 Description

The DRV880x provides a versatile motor driver

solution with a variety of capabilities. The device

contains a full H-bridge which can be used to drive

a brushed DC motor, one winding of a stepper motor,

or other devices such as solenoids. A simple PHASEENABLE

interface allows easy interfacing to controller

circuits.

The output stages use N-channel power MOSFETs

configured as an H-bridge. The DRV880x is capable

of peak output currents up to ±2.8 A and operating

voltages up to 36 V. An internal charge pump

generates the needed gate drive voltages.

A low-power sleep mode is provided which shuts

down internal circuitry to achieve a very low quiescent

current draw. This sleep mode can be set using a

dedicated nSLEEP pin.

Internal protection functions are provided for

undervoltage, charge pump fault, overcurrent, shortto-

supply, short-to-ground, and overtemperature. Fault

conditions are indicated through the nFAULT pin.

The DRV880x is packaged in a 16-pin WQFN

package with PowerPAD™ (Eco-friendly: RoHS & no

Sb/Br).
