リレーの駆動回路。[Scope of Claim for Utility Model Registration] A power-off detection circuit that outputs a power-on detection signal after a predetermined time has elapsed after the power is turned on, and rapidly outputs a power-off detection signal when the power is turned off; A set coil and a reset coil of the latching relay, a capacitor charged by the power supply voltage, a first transistor connected to the reset coil and driven by a reset signal, and an output of the power-off detection circuit connected to the reset coil. A second transistor is provided with a second transistor that is driven by a signal, and a third transistor that is connected to the set coil and is driven by a set signal. The relay is configured such that power is supplied to the reset coil through the second transistor, and when the power is cut off, current is supplied to the reset coil through the second transistor by the discharge voltage of the capacitor to reset the relay. Latching relay drive circuit.
