M56788FP
5 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56788FP is a semiconductor integrated circuit in order 5ch
actuator.
FEATURES
● Low saturation voltage.
● 3.3V DSP available.
● There are two motor power supplies.
Vm1 CH1,2 motor power supply-1
Vm2 CH3,4,5 motor power supply-2
● Built-in OP amp. for Regulator.
(It enables a Regulator which consists of external PNP Tr.s and
resistors.)
● Flexible Input amp. setting.(It enables PWM control.)
● Low cross-over distortion.(4.5V–13.2V)
● Wide supply voltage range.(4.5V–13.2V)
● Built-in Thermal Shut Down circuit.
● Built-in Mute circuit.(two systems)
MUTE1:CH1–4, MUTE2:CH5
APPLICATION
MD, CD-audio, CD-ROM, VCD,DVD etc.
