Begin by connecting pin 85 of the relay to a clean ground point on the vehicle chassis or the negative terminal of the battery. Then connect pin 86 to the ignition switch wire — this is the wire that ...

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 purpose of this article is to walk through the steps of implementing a ripple injection circuit for constant on-time POLs. It covers how to connect the circuit and then how to calculate the values ...
