M56789FP

4 CHANNEL ACTUATOR DRIVER

DESCRIPTION

The M56789FP is a semiconductor integrated circuit in order to
drive 4ch actuator.

FEATURES

●Large power dissipation (Power Package).

●3.3V DSP available.

●Low saturation voltage (typical 0.6V at load current 500mA).

●Low cross-over distortion.

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

●Divided Motor power supplies into three parts.

●Ch1, Ch2 and Ch3 can be controlled by PWM.

●Ch1 and Ch2 can act in the Current Control mode.

●Two naked Operational Amplifiers.

●TSD(Thermal Shut Down) circuit.

●Two mute circuits.

APPLICATION

CD-ROM, DVD, DVD-ROM etc.
