MITSUBISHI <CONTROL / DRIVER IC>
I/O TERMINAL EQUIVALENT CIRCUIT
(7) CH1,CH2 power amplifier output terminal equivalent circuit
(8) CH3 power amplifier output terminal equivalent circuit

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.
