Galvanic Isolated 8 Channel High-Side Switch (0.6A per channel)

https://www.electronics-lab.com/galvanic-isolated-8-channel-high-side-switch-0-6a-per-channel/

This project provides 8 fully protected and isolated high-side power switches that are able to handle current up to 625 mA. An 8-bit parallel microcontroller compatible interface allows connecting the inputs directly to a microcontroller or standalone circuit system. The input interface also supports direct control mode and is designed to operate with 3.3/5V CMOS […]

Sensing current on the high side

https://www.electronics-lab.com/home-community-blogs-benchtalk-sensing-current-high-side/

Michael Dunn@ edn.com discuss about current sense on the high side of power source. At their heart, the majority of DC current sense circuits start with a resistance in a supply line (though magnetic field sensing is a good alternative, especially in higher-current scenarios). One simply measures the voltage drop across the resistor and scales […]
