台湾致新 G2057BF11U SOP-8 代理商主推

　　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.
