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 ...

Providing a rugged interface between standard logic and 3 to 6-V dc inductive loads, the DRDC3105 relay driver is designed to handle relays, solenoids, incandescent lamps and small motors in a wide ...

[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 ...

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 ...

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 ...

A LIN pre-driver IC for relay DC motors from Melexis includes 48 KB of memory (16 KB ROM for the included LIN protocol and 32 KB Flash for the application software. The MLX81160 is the latest addition ...
