M56759AFP
DESCRIPTION
The M56759 is a semiconductor integrated circuit designed for a CD-ROM actuator driver. This device can function 4-channelactuators by 1 chip due to include 4 channel BTL drivers. Three channels of this device, ch1, ch2 and ch3 can be controlled by PWM pulse. Two of them, ch1 and ch2 can also act in the Current Control mode. Furthermore, this device includes two mute circuits and TSD function.
