Teardown and exploration of Apple’s Magsafe connector

Teardown and exploration of Apple’s Magsafe connector.

Since you’ve done a lot with Apple chargers, I thought you might be interested in my article on the Magsafe connector on Mac chargers. I tore down the charger connector, determined that it communicates with the Mac via the 1-wire protocol and a DS2413 1-wire switch chip, and I used an Arduino to read the charger’s ID and control the status light.

All the best,
Ken
