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.
