TIC10024QDCPRQ1 Description

The TIC10024QDCPRQ1 is an advanced Multiple Switch Detection Interface (MSDI) device designed to detect external switch status in a 12-V automotive system. The TIC10024QDCPRQ1 features a comparator with adjustable thresholds to monitor digital switches independently of the MCU. The device monitors 24 direct switch inputs, with 10 inputs configurable to monitor switches connected to either ground or battery.
