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 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, 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).
