Low-Cost 22-CH Multiple Switch Detect Interface

CD1020
正常供应

CD1020是一款经济型开关检测接口(MSDI)，可检测多达22个开关触点的关闭和开启。开关状态(开启或关闭)会通过一个串行外设接口(SPI)传输至微处理器(MCU)。该SMARTMOS器件还具备一个22对1模拟复用器，将输入通道换用为模拟输入。模拟精选的输入信号经过缓冲，并且在AMUX输出引脚上提供以供MCU读取。

CD1020器件有两种工作模式，正常模式和低功耗模式(LPM)。正常模式允许对器件进行编程，在检测到开关状态变化时，为开关触点提供上拉或下拉电流。 LPM提供低静态电流，使CD1020成为面向需要低睡眠状态电流的汽车和工业控制产品的理想之选。

低成本MSDI采用高功率、节省空间的可润湿侧翼5x5mm QFN封装。
