GMT G2056F11U Low-Voltage H-Bridge Driver

General Description  

The G2056x family of devices provides an integrated  motor driver solution for cameras, consumer products,  toys, and other low-voltage or battery-powered motion  control applications. The device can drive one dc motor  or other devices like solenoids. The output driver block  consists of N- channel power MOSFETs configured as  an H-bridge to drive the motor winding. An internal  charge pump generates needed gate drive voltages.  

The G2056x family of devices can supply up to 1.8A of  output current. It operates on a motor power supply  voltage from 0 to 11V, and a device power supply  voltage of 1.8V to 7V.  The G2056 device has a PWM (IN1-IN2) input interface; the G2056A device has a PH-EN input interface;.  Both interfaces are compatible with in dustry-standard  devices. 

Internal shutdown functions are provided for overcurrent protection, short-circuit protection, undervoltage  lockout, and overtemperature.
