GMT 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.
