Device Enables a Single MCU to Monitor 24 Automotive Switches
Maxim Integrated Products introduces the MAX13362, a 24-channel switch-contact monitor for automotive switches. This device enables a single microcontroller to monitor up to 24 mechanical switches distributed throughout the automobile, thus eliminating the expense of multiple remote MCUs. The MAX13362 protects low-voltage circuitry from high voltages (27 V, max) and reverse-battery conditions, making it appropriate for monitoring remote mechanical switches that are exposed to adverse conditions. The device also offers three modes of operation (continuous, polling, and shutdown) to optimize power consumption. The MAX13362 is ideal for automotive body controllers and door modules. An SPI interface provides multiple programming options.
