3. Function description
GC8833C is a dual channel, 12V DCmotor drive, continuous current 0.8A, peakcurrent 1.5A, can be used in toys, printers,industrial control and other fields.
The chip can drive a stepper motor or twoDC motors, and can also be used to driveother magnetic loads.
The output H-bridge of the chip integratescurrent limiting function, and each powerMOS transistor is provided with over-currentprotection and short-circuit protection.
The chip has FLAG pin, when thetemperature is too high, the voltage is too low,or the output short circuit, the outputindication signal

When all logic inputs are low, the powersaving current is less than 1uA
