Traditional relay drivers involve multiple discrete components to drive the relay and protect against damage to the microcontroller or other devices that can be caused by the voltage spike generated ...

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 ...

[Bart] built a couple dozen Pololu compatible relay drivers. If you have a Reprap, you’re probably familiar with the Pololu stepper motor driver. These tiny pieces of kit provide stepper motor control ...

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 ...

A recent application required the microcontroller to be able to switch some high-reliability latching relays as a safety backup for normal solid-state switching. A recent application required the ...

The A2550 relay combines the functions of a voltage regulator, watch-dog, and reset, with three low-side DMOS relay driver outputs. Primarily targeted at automotive applications, the IC performs over ...
