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 ...

[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 ...

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. In these ...

PWM relays allow engineers to go beyond simple "on-off" control to realize significant power savings and reduced heat ...

[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 ...
