A relay is an electro-magnetic switch which is useful if you want to use a low voltage circuit to switch on and off a light bulb.You can use that circuit to drive a relay of 12 V with a trigering signal of 5V. It uses 2 diodes 1N4002 , 1 transistor 2N3904 and two resistors.By changing the resistors value you can change the input triggering voltage.This Relay Driver is intended to replace an array of three to six discrete components with an integrated SMT part. It can be used to switch 3 to 6 Vdc inductive loads such as relays, solenoids, incandescent lamps and small DC motors without the need of a free-wheeling diode.This Relay Driver is intended to replace an array of three to six discrete components with an integrated SMT part.
