Texas Instruments' TIC12400 are advanced MSDI devices designed to detect external switch statuses. The TIC12400 support 24 direct inputs, with ten inputs configurable to monitor digital I/O switches. Six wetting current settings can be programmed for each input to support different application scenarios. The TIC12400 feature an integrated 10-bit ADC to monitor multi-position analog switches and a comparator to monitor digital switches independently of the MCU. The devices support wake-up operation on all switch inputs to eliminate the need to keep the MCU active continuously, reducing power consumption of the system. The TIC12400 support two modes of operations: continuous and polling mode. In continuous mode, wetting current is supplied continuously. In polling mode, wetting current is turned on periodically to sample the input status based on a programmable timer, reducing the system power consumption significantly. The TIC12400 also offer various fault detection and diagnostic features for improved system robustness.
