Switch sensor monitoring device that interfaces directly with the resistance-coded switch.

TI announced the launch of two new MSDI products that consume up to 98 percent less system power than existing solutions.

The TIC12400 and TIC12400-Q1 are the first switch sensor monitoring devices capable of directly interfacing with resistive-coded switches.

The TIC12400 and TIC12400-Q1 can solve this problem by fundamentally monitoring the inputs and decoding the resistive paths of as many as 54 switches in a single device, offloading the processor from having to decode the switching signals.

Additionally, it can significantly reduce system power consumption in applications such as automotive body electronics and factory and building automation equipment by directly monitoring 24 channel inputs, providing internal diagnostic capabilities, and reducing system microcontroller execution time using a polling sequence architecture.

In applications requiring high efficiency, system power consumption can be reduced from milliamps to microamps. Direct on-device monitoring allows the microcontroller to enter a low-power sleep mode, consuming less power when idle. This is essential for vehicles with start/stop functionality or when the vehicle is parked for extended periods.

The TIC12400-Q1 reduces the number of individual components by up to 120, enabling the monitoring of up to 54 switches and sensors through input sharing and matrix mode. Additionally, as a highly integrated solution, it can control wetting current, timing control, threshold values, and includes redundant circuitry for protection, thereby increasing system-level reliability and reducing potential failure points.
