M56783AFP

3 CHANNEL ACTUATOR DRIVER

DESCRIPTION

The M56783AFP is a semiconductor integrated circuit in order to
drive 3ch actuator.

FEATURES

●3.3V DSP available.

●Low saturation voltage.

●By taking advantage of the bootstrap function, the saturation

voltage can be lower.

●There are two motor power supplies.
Vm12 CH1, 2 motor power supply-1
Vm3 CH3 motor power supply-2

●7V power-supply is possible (Vm12 = 12V and MGND12 = 5V)

●Flexible Input amplifier setting. (It enables PWM control.)

●CH1 and CH2 can act in the Current Control mode.

●Low cross-over distortion.

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

●Including Thermal Shut Down circuit.

●Including 2 Operational Amplifiers.

●Including Mute circuit (2 lines).

APPLICATION

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

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.

This IC has two MUTE terminal (MUTE1 and MUTE2).
It is possible to control ON / OFF of each circuit (CH1, CH2, CH3,
etc) by external logic inputs.
The table 1 shows its function.
In case of both MUTE1 and MUTE2 is LOW or OPEN, the bias of
all circuit becomes OFF.

The equivalent circuits of an output stage of the power amplifiers
are shown in (7).
The power supplies of CH1, CH2 are Vm12.
And the power supplies of CH3 are Vm3.
The source side of the power amplifier output stage consists of a
PNP and a NPN.
The emitta of the PNP is connected to VBS. So the power of the
PNP supplies can be adjusted externally.

About bootstrap advantage
The output stage of the power amplifiers consists of the preceding
components. If VBS is provided with higher voltage input than Vm*
(The recommendation voltage is Vm+1V) externally, the output
range can be wider than that of VBS = Vm.
Please take advantage of this bootstrap function for the system
which has many power supplies. And it is the same with the
external bootstrap circuit which provides VBS with higher voltage
inputs than Vm*.
Also the bootstrap can decrease the saturation voltage at the
source side of the power amplifier output stage. Therefore, when
the outputs of the power amplifiers which drive motors and
actuators are fully swung, the power dissipation of the IC will be
decreased.
