MITSUBISHI <CONTROL / DRIVER IC>
M56789FP
4 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56789FP is a semiconductor integrated circuit in order to
drive 4ch actuator.
FEATURES
q Large power dissipation (Power Package).
q 3.3V DSP available.
q Low saturation voltage (typical 0.6V at load current 500mA).
q Low cross-over distortion.
q Wide supply voltage range.(4.5V–13.2V)
q Divided Motor power supplies into three parts.
q Ch1, Ch2 and Ch3 can be controlled by PWM.
q Ch1 and Ch2 can act in the Current Control mode.
q Two naked Operational Amplifiers.
q TSD(Thermal Shut Down) circuit.
q Two mute circuits.
APPLICATION
CD-ROM, DVD, DVD-ROM etc.
