The ULN2003V12 is a low power upgrade of TI’s popular ULN2003 family of 7-channel Darlington transistor array. The ULN2003V12 sink driver features 7 low output impedance drivers that minimize on-chip ...
A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...
The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...
An electrical relay is a type of heavy-duty, remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current. Relays install between the ...
