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 Allegro A2550 combines the functions of voltage regulator, watchdog, and reset, as well as three low-side DMOS relay driver outputs. Primarily targeted at automotive applications, this IC is ...

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 usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

[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 ...
