Automotive Switch/Contact Monitors

Automotive contact monitor and level shifters such as the MAX13036 monitor and debounce eight remote mechanical switches while consuming a meager 17 µA (typical) supply current. The low supply current is a result of innovative ultralow current design techniques, as well as the use of programmable polling periods. The device's low current consumption combined with a wide input-voltage range (±45 V), high ±8 kV ESD protection on switch inputs, and adjustable wetting current make the MAX13036 ideal for applications within harsh automotive environments, such as body computers, window lifters, electric sunroofs, and other electronic control units (ECUs).
