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.

MUTE FUNCTION
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. Therefore, this mode is available in order to reduce the power dissipation when the waiting mode.

VBS Vm12
VM*
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.
