... DESCRIPTION The M56783AFP is a semiconductor integrated circuit in order to drive 3ch actuator. FEATURES 3.3V DSP available. Low saturation voltage. By taking advantage of the bootstrap function, the saturation voltage can be lower. There are two motor power supplies. Vm12 CH1, 2 motor power supply-1 Vm3 CH3 motor power supply-2 7V power-supply is possible (Vm12 = 12V and MGND12 = 5V) Flexible Input amplifier setting ...

... VM3* inputs than Vm*. Also the bootstrap can decrease the saturation voltage at the source side of the power amplifier output stage. Therefore, when the outputs of the power amplifiers which drive motors and actuators are fully swung, the power dissipation of the IC will be decreased. M56783AFP ...
