Abstract
In a switch device, an output voltage output by a microcomputer is input to one end of a resistor. A driving circuit switches a main switch on or off according to a resistor voltage at the other end of the resistor. When all of a plurality of specific voltages included in a plurality of output voltages output by the microcomputer are an output threshold or more, an AND circuit of an adjustment circuit reduces the resistor voltage.
Claims8
A switch device comprising:
- an output unit configured to output a plurality of voltages;
- a switch;
- a resistor whose one end receives one output voltage output by the output unit;
- a switching circuit configured to switch the switch on or off according to a resistor voltage at the other end of the resistor;
- and
- a reduction circuit configured to, when all of a plurality of specific voltages included in the plurality of output voltages output by the output unit are an output threshold or more, reduce the resistor voltage.
