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 ...

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 ...

Active clamp structure prevents overvoltage when inductive load is switched off TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO: 6502) today announced that it has launched a MOSFET, "SSM3K337R", ...

[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. Allegro’s ...
