限抵抗を挿入したことを特徴とするタイマ回路。 A circuit that outputs the cathode of a programmable unification transistor in which a divided voltage obtained by dividing the power supply voltage using a voltage dividing resistor is applied to the gate, and the charging voltage of the capacitor charged from the power supply via the resistor is applied to the anode. The timer circuit is connected to the control terminal of the capacitor, and when the charging voltage of the capacitor exceeds the divided voltage, the programmable union transistor turns on and drives the output circuit. A timer circuit characterized by inserting a resistor.
