Description

The AW8638 provides an integrated motor driver
solution for cameras, consumer products, toys, and
other low-voltage in battery-powered motion control
applications. The device can drive one dc motor in
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 AW8638 can supply up to 1.9A of output
current. It operates on a motor power supply
voltage from 1.8V to 12V, and a device power
supply voltage of 1.8V to 5.5V.
The AW8638 has a PH-EN input interface, witch is
compatible with industry standard devices.
Internal shutdown functions are provided for Overcurrent
protection, Short-circuit protection, Undervoltage
lockout, and Over-temperature protection.
