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 ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...

Allegro's A2550 automotive relay driver incorporates a 5-V regulator. Large numbers of relay-based applications require the use of a microprocessor that implements a complex system control. Dec. 26, ...

[Glitch] got his hands on a slew of relays which are meant for use in industrial equipment. They are designed to operate at 24V. He wanted to use these with common microcontrollers and instead of ...

[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 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 ...

After getting patent rights from the United States Patent and Trademark Office (USPTO) last month for its driver relay model, Gurugram-based logistics startup Rivigo has launched a Relay-as-a-Service ...
