MITSUBISHI M56758FP 5 CHANNEL ACTUATOR MOTOR DRIVER DESCRIPTION The M56758FP is a semiconductor integrated circuit designed for a actuator driver used for MD, CD-audio, etc. This device can function 5-channel-actuators by 1 chip due to include 5 channel BTL drivers. Sufficient output dynamic range can be obtained by low supply voltage because saturation voltage of power output is low. All channels include level shift circuit in order that output swings most suitably although reference voltage of signal disposal system in each system becomes 1.5V. And, differential PWM control is possible since all channels are composed of Differential input structure. Also, as this device includes general purpose OP amp, it is suited to wide-ransing application. Further more, this devise is able to power save since it includes mute circuit.
