M56788FP
5 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56788FP is a semiconductor integrated circuit in order 5ch
actuator.
FEATURES
q Low saturation voltage.
q 3.3V DSP available.
q There are two motor power supplies.
Vm1 CH1,2 motor power supply-1
Vm2 CH3,4,5 motor power supply-2
q Built-in OP amp. for Regulator.
(It enables a Regulator which consists of external PNP Tr.s and
resistors.)
