The AW8637 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 AW8637 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 AW8637 has a PWM (PWM1-PWM2) input interface, witch is compatible with industry standard devices.
Internal shutdown functions are provided for Over-current protection, Short-circuit protection, Under-voltage lockout, and Over-temperature protection.
