4-CHANNEL ACTUATOR DRIVER
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.
FEATURES
● Low saturation voltage (at bootstrap).
●(typical 0.7V at load current 500mA)
●Wide supply voltage range.
(4.5V to 13.2V)
●Low cross-over distortion.
●Two naked Operational Amplifiers
●Divided Motor power supplies into three parts
