MITSUBISHI <CONTROL / DRIVER IC>
M56783AFP
3 CHANNEL ACTUATOR DRIVER
DESCRIPTION
The M56783AFP is a semiconductor integrated circuit in order to
drive 3ch actuator.
FEATURES
q 3.3V DSP available.
q Low saturation voltage.
q By taking advantage of the bootstrap function, the saturation
voltage can be lower.
q There are two motor power supplies.
Vm12 CH1, 2 motor power supply-1
Vm3 CH3 motor power supply-2
q 7V power-supply is possible (Vm12 = 12V and MGND12 = 5V)
q Flexible Input amplifier setting. (It enables PWM control.)
q CH1 and CH2 can act in the Current Control mode.
q Low cross-over distortion.
q Wide supply voltage range. (4.5V – 13.2V)
q Including Thermal Shut Down circuit.
q Including 2 Operational Amplifiers.
q Including Mute circuit (2 lines).
APPLICATION
MD, CD-audio, CD-ROM, VCD, DVD etc.

3.9W using K-type board
2.9W using L-type board
2.6W using M-type board
This IC’s package is POWER-SSOP, so improving
the board on which the IC is mounted enables a large
power dissipation without a heat sink.
For example, using an 1 layer glass epoxy resin
board, the IC’s power dissipation is 2.6W at least. And
it comes to 3.9W by using an improved 2 layer board.
The information of the K, L, M type board is shown in
the board information.
