Abstract:
The present invention relates to a driving circuit for relay, which uses N relays with their coils coupled to each other. One of the relays is coupled to a driving power supply. A switching control circuit is coupled to a second relay and a reference voltage for controlling on/off of the plurality of relays. A driving control circuit is coupled to the plurality of relays for controlling excitation of the plurality of relays. After the coils of the relays are excited by the driving control circuit, the voltage of a single coil is dropped to one Nth of the driving voltage. Thereby, the power consumption of the coils of the relays can be reduced, and hence enhancing the lifetime and reliability of the relays.
