Integrated or discrete load switch: which one should you use? (Part 1 of 2)

MOSFET-based load switches, whether as an integrated circuit (IC) or built with discrete components, continue to be popular choices for many engineers. They are favored in power-switching applications ...

Two-IC circuit combines digital and analog signals to make multiplier circuit

The circuits presented here use ananalog switch—such as a DG419or one-third of a CD4053—to combinean analog signal with a standard PWMsignal. Most microcontrollers can easilygenerate the PWM signal.

A Motion Activated AC Switching Circuit Using Mostly Discrete Components

If you’ve ever dealt with a brightly lit Christmas tree, you might understand the frustration of having to crawl underneath the tree to turn the lights on and off. [brmarcum] feel’s your pain. He’s ...
