MITSUBISHI <CONTROL / DRIVER IC> (VM1(+), VM1(-), VM2(+), VM2(-)) I/Oterm inalequivalentcircuit (7)CH1,CH2 power I/O terminal equivalent circuit The equivalent circuits of an output stage of power amplifiers are shown in(7) and(8) . The power supplies of CH1, CH2 are Vm1. And the power supplies of CH3, CH4, CH5 are Vm2. The source side of the power amplifier output stage consists of a PNP and a NPN. In the case of the CH1 and CH2, the emitta of the PNP is connected to VBS1, and in the case of the CH3, CH4 and CH5, it is connected to VBS2. So the power supplies of the PNP can be adjusted externally. (VM3(+), VM3(-), VM4(+), VM4(-), VM5(+), VM5(-)) (8)CH3,CH4,CH5 power amplifier output terminal equivalent circuit [About bootstrap advantage] The output stage of the power amplifier consists of the preceding components. If VBS* is provided with higher voltage input than Vm*(The recommendationvoltage 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. VBS2 GND VM Vm2 TH ERM A L D ERAT IN G 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 3.6W by using an improved 2 layer board. The information of the N, P type board is shown in the board information.
