24-channel microcontroller

  • 21-Sep-2009 03:24 EDT

Maxim Integrated Products’ MAX13362 24-channel switch-contact monitor is designed for use in automotive applications.The device enables a single microcontroller to monitor the status of up to 24 mechanical switches distributed throughout the automobile, thereby eliminating the expense of multiple remote microcontrollers. Suitable for use in automotive body controllers and door modules, MAX13362 protects low-voltage circuitry from high voltages (27 V maximum) and reverse-battery conditions, making it suitable for monitoring remote mechanical switches that are exposed to adverse conditions. Fully specified over the -40 to +125°C (-40 to +257°F) automotive temperature range, the device also features three modes of operation (continuous, polling, and shutdown) to optimize power consumption. A serial peripheral interface bus provides multiple programming options. Users can configure polling time and polling active time to conserve power between monitoring events as well as program wetting current, interrupt capability, and switch configuration (i.e., battery connected or ground connected).
