In-vehicle 24-input multi-switch detection interface 'TIC12400-Q1'
The TIC12400-Q1 is a multi-switch detection interface (MSDI) for external switches in 12V automotive systems. It employs an integrated 10-bit ADC to monitor digital switches independently from the MCU, utilizing multi-position analog switches and comparator monitoring. The detection thresholds for the ADC and comparator are programmable, supporting various switch topologies and system non-idealities. It monitors 24 direct switch inputs, with 10 inputs configurable for switch monitoring connected to ground or battery. Six unique wet current settings can be programmed for individual inputs to support differential application scenarios. 【Features】 ■ AEC-Q100 compliant ■ Supports 12V automotive systems with overvoltage/voltage drop warning functions ■ Configurable for 10 inputs for switch monitoring connected to ground or battery, monitoring up to 24 direct switch inputs *For more details, please contact us.
