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 PHASE-
ENABLE interface allows easy interfacing to
controller circuits.
The output stages use N-channel power MOSFETs
configured as an H-bridge. The DRV880xis 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, short-
to-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).
