TIC12400DCPR-24-Input Sensor Monitor With SPI Interface

The TIC12400 is an advanced Multiple Switch Detection Interface (MSDI) device designed to detect external switch statuses. The TIC12400 supports 24 direct inputs, with 10 inputs configurable to monitor digital I/O switches. 6 wetting current settings can be programmed for each input to support different application scenarios. The TIC12400 features an integrated 10-bit ADC to monitor multi-position analog switches and a comparator to monitor digital switches independently of the MCU. The device supports wake-up operation on all switch inputs to eliminate the need to keep the MCU active continuously, thus reducing power consumption of the system. The TIC12400 supports 2 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, thus the system power consumption is significantly reduced. The TIC12400 also offers various fault detection and diagnostic features for improved system robustness.
