Relay Driver Using Transistor at John Whyte blog

Relay Driver Using Transistor. we will first go over how to build a relay driver circuit for relays which operate from dc power. To drive a dc relay, all we need is sufficient dc voltage which the relay is. Relay power may be sourced by a higher, unregulated. a typical relay switch circuit has the coil driven by a npn transistor switch, tr1 as shown depending on the input voltage level. for an embedded application, i'd like to drive a relay using a transistor. all the relay driver circuits above are the pulse output of the digital circuit to control a transistor. a microcontroller typically will output a high or low logic level (3.3 or 5v for a high, and 0 volts for a low) and is used to switch on a driver transistor. below is the circuit of a relay driver using the npn transistor bc 548. uses more commonly available and less expensive npn drive transistors. At the moment i'm experimenting with a bc547, but.
