M56748FP
4-CHANNEL ACTUATOR MOTOR DRIVER
DESCRIPTION
The M56748FP is a semiconductor IC developed as the motor
driver used to CD player, CD-ROM.
This circuit includes Standby circuit, TSD circuit and 4-Channel
BTL Driver that is able to drive four actuator with one IC.
FEATURES
●Low Output saturation voltage (typ:1.35V,at 0.5A)
● Large Operating supply voltage range (4.5 – 15V)
● Minimum Crossover distortion
APPLICATION
CD player, CD-ROM, Video CD
