3 说明

TIC10024-Q1 是一款先进的多开关检测接口 (MSDI) 器件，用于检测 12V 汽车系统中的外部开关状态。TIC10024-Q1 配有可调阈值的比较器，可以独立于 MCU 的方式监控数字开关。该器件监控多达 24 路直接开关输入，并可配置其中 10 路输入以监控接地或连接到电池的开关。可为每路输入设定 6 种独特的湿性电流设置，从而支持不同的应用场景。该器件支持所有开关输入的唤醒操作，因此无需持续使 MCU 保持活动状态，进而可降低系统功耗。TIC10024-Q1 还提供集成故障检测和 ESD 保护功能，从而提高系统稳健性。TIC10024-Q1 支持 2 种工作模式：连续模式和轮询模式。连续模式下将连续提供湿性电流。轮询模式下将根据可编程计时器来定期接通湿性电流以对输入状态进行采样，从而显著降低系统功耗。
