Abstract
PURPOSE:To prevent the overvoltage for the device, by producing the switch circuit control signal through a comparison between the input voltage and the power supply voltage and then securing a switch action by the control signal. CONSTITUTION:A comparison is given through the comparator 7 between the power supply voltage VDD and the input voltage Vin which is obtained via the input protecting circuit 5 and to be applied to the device 1. And in the case of Vin<=VDD, the transistor 31 of the switch circuit 8 has an on-action to apply the voltage VDD to the device 1. In case the input voltage is overvoltage, i.e., in the case of Vin> VDD, the output signal is obtained through the comparator 7. Thus te transistor 31 is turned off, and then the power supply circuit is cut off to the device 1 to given on-control to the device 1. In this way, the device can be protected by cutting off the overcurrent flowing between the VDD of the device can be protected by cutting off the overcurrent flowing between the VDD of the device 1 and the earth VSS.
