I have listed a few basic relay drivers for your reference. Included are the following: High side toggle switch driver, low side toggle switch driver, bipolar NPN transistor driver, Darlington ...

This schematic highlights the mechanical nature ... When the 4-bit LUT0 goes HIGH, it will activate the relay driver operation and ACTIVE (PIN17) will flag HIGH. The OCP and UVP inputs can be ...

From there, a relay can be hooked up to the driver to control the spindle for a router, or a whole bunch of fans for a homebrew laser cutter. The schematic and Gerber files are up on [Bart]’s ...

Often a need arise to interface output of the microcontroller with an electromagnetic relay (EMR). Relays are devices which ... Galvanic Isolation says that the driver circuit is separated from the ...

He wanted to use these with common microcontrollers and instead of buying a driver he designed and built ... of the design he was able to control the relay using 3.3V, 5V, or 12V.

Texas Instruments (TI) has introduced what it claims is the industry's first fully integrated, seven channel relay driver that can support low voltage relays from 1.8 to 5V. The ULN2003LV is designed ...
