In addition, considering variations in the output terminal state of the switching integrated circuit 3 itself with respect to the control voltage VCONT, changes in Vcc voltage due to changes in the power supply voltage of the set, and variations in the resistance value of the resistor Ra-Re of the remote controller 2, etc. 2
It is difficult to guarantee the operation of each of the switches Swa to Swe. Taking temperature characteristics as an example, remote controller 2
To guarantee the operation of each switch, the control voltage VC must be within the range shown by the arrow for each switch, as shown in Figure 4.
ONT must be configured. Wait, the switching integrated circuit 3 generally has characteristics that differ between lots, so it is very difficult to set the control voltage VCONT.
