The MAX13362 is a 24-channel automotive switch monitor. To avoid the necessity of adding numerous external components, which would increase the application cost and possibly make reliable contact-resistance measurement more difficult, the MAX13362 was carefully designed to be robust. The device monitors the status of 24 remote switches in an automobile while withstanding automotive transients and performing well during the many anomalous automotive test conditions. Since the device interfaces to remote switches in the vehicle, it is directly subjected to all the transients observed in the wiring harness of an automobile.

This article documents how the MAX13362 reacts in many circumstances encountered during automotive ECU-level testing. The article describes the tests performed and the results obtained.
