特性
符合汽车应用要求
具有符合 AEC-Q100 标准的下列特性:
器件温度等级 1:–40°C 至 125°C 的工作环境温度范围
器件 HBM ESD 分类等级 H2
器件 CDM ESD 分类等级 C4B
提供功能安全
有助于进行功能安全系统设计的文档
旨在支持 12V 汽车系统,并提供过压和欠压警告
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
开关输入可承受高达 40V 的电压(负载突降条件)和低至 -24V 的电压(反极性条件)
6 种可配置的湿性电流设置:
(0mA、1mA、2mA、5mA、10mA 和 15mA)
适用于数字开关监控并具有 4 个可编程阈值的集成比较器
轮询模式下的超低工作电流:
68μA 典型值(t
POLL
= 64ms,t
POLL_ACT
= 128μs,
全部 24 路输入均有效,比较器模式,所有开关均打开)
使用 3.3V/5V 串行外设接口 (SPI) 协议直接与 MCU 对接
可产生中断来支持所有输入的唤醒操作
采用适当的外部组件根据 ISO-10605 在输入引脚上实现 ±8kV 接触放电 ESD 保护
38 引脚 TSSOP 封装
