圧供給優先制御回路。 Turns the line ON/OFF in the voltage supply priority control circuit that supplies positive and negative polarity voltages to ICs, etc.
In order to control the ON/OFF operation of the FET transistor, a bias resistor is provided to bias the FET transistor, so that under any conditions when the power is turned on, the positive voltage reaches the load before the negative voltage. A voltage supply priority control circuit characterized in that the voltage is supplied.
