General Description
The G2057/G2057A 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 G2057/G2057A 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 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 and G2057A are both packaged in SOP-8(FD)package.
