G2057BF11U    Full-Bridge PWM Motor Driver

General Description

The G2057X contained G2057,G2057A, G2057B 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.

Two logic inputs provide directly interfacing to controller

circuits.

The output stages use four N-channel power MOSFETs

configured as an H-bridge. The G2057X capable of

peak output currents up to ±3.5A and operating voltages

up to 40V.

A low-power standby mode is provided which shuts

down internal circuitry to achieve a very low quiescent

current draw.

The G2057/G2057B device features an adjustable

PWM current limit at VSEN pin. And G2057A provided a

fixed current limit 0.35V.

Internal protection functions are provided for

undervoltage(UVLO), overcurrent(OCP), short-to-supply,

short-to-ground, and overtemperature(OTS). Fault conditions

are indicated through the nFAULT pin.

The G2057, G2057A and G2057B are both packaged in

SOP-8 (FD) package
