EEVblog #1164 – Xbox Engineering Baptism Of Fire

A retro look at the 2005 Xbox 14 million unit power cord replacement issue and a teardown and analysis of the supplied protection device from Microsoft.
Some interesting engineering lessons to be learned.
UPDATE: Apparently what this is an “Arc Fault Circuit Interrupter” (AFCI) that continually monitors the current for the presence of arcs caused by such an intermittently faulty power connection. Hence the complexity and micro with ADC to monitor the current.
