[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 ...
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 ...
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 ...
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. Dec. 26, ...
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 ...
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 ...
