The equivalent circuits of an output stage of the power amplifier are shown in (7) . The power supplies of CH1,CH2 are Vm1. The power supply of CH3 is Vm3, and the power supply of CH4 is Vm2. The source side of the power amplifier output stage consists of a PNP and a NPN. The emitta of the PNP is connected to VCC2. So the power supplies of the PNP can be adjusted externally. [About bootstrap advantage] The output stage of the power amplifier consists of the preceding components. If VCC2 is provided with higher voltage input than Vm* (The recommendation voltage is Vm*+1V) externally, the output range can be wider than that of VCC2=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 VCC2 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.

3.6W using N-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 3.6W by using an improved 2 layer board. The information of the N, P type board is shown in the board information.
