The AW86308 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 AW86308 can supply up to 1.2A of output current. It operates on a motor power supply voltage from 0V to 12V, and a device power supply voltage of 1.8V to 5.5V.
The AW86308 device has advanced current regulation circuitry that does not use an analog voltage reference or external sense resistor. This novel solution uses a standard low-cost, low-power resistor to set the current threshold. The ability to limit current to a known level can significantly reduce the system power requirements and bulk capacitance needed to maintain stable voltage, especially for motor startup and stall conditions.
Internal shutdown functions are provided for Over-current protection, Short-circuit protection, Under-voltage lockout, and Over-temperature protection.
