M56758FP

5 CHANNEL ACTUATOR MOTOR DRIVER

DESCRIPTION

The M56758FP is a semiconductor integrated circuit designed for a
actuator driver used for MD, CD-audio, etc. This device can
function 5-channel-actuators by 1 chip due to include 5 channel
BTL drivers.
Sufficient output dynamic range can be obtained by low supply
voltage because saturation voltage of power output is low. All
channels include level shift circuit in order that output swings most
suitably although reference voltage of signal disposal system in
each system becomes 1.5V. And, differential PWM control is
possible since all channels are composed of Differential input
structure. Also, as this device includes general purpose OP amp, it
is suited to wide-ransing application. Further more, this devise is
able to power save since it includes mute circuit.

FEATURES

●3.3V DSP available

●Low saturation voltage.

(Typical 1.35V at load current 0.5A and no bootstrap condition.)
Absolute maximum rating of load current: CH1 – 5 500mA
A bootstrap function is 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. (Enables Regulator structure by
using external PNP Tr. and resistor.)

●Flexible Input amp. setting.
Enables PWM control.

●Low cross-over distortion.

●Wide supply voltage range. (4.5V – 13.2V)

●Built-in Thermal protection.

●Built-in Mute circuit. (two systems)

MUTE1: CH1 – 4, MUTE2: CH5

APPLICATION

MD, CD-audio, CD-ROM, VCD, DVD etc.
