[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 ...

[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 ...

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 ...

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 ...

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 ...

Designed for relay-based applications requiring a microprocessor, the A2550 automotive-grade relay driver integrates a voltage regulator, watchdog and reset, and three low-side DMOS relay-driver ...

Electrical appliances such as lights, fans, air-conditioners, TVs, and water pumps are typically operated using manual ...
