数据: TMP411 ±1°C Remote and Local Temperature Sensor With N-Factor and Series Resistance Correction 数据表
TMP411设备是一个带有内置本地温度传感器的远程温度传感器监视器。远程温度传感器,二极管连接的晶体管通常是低成本,NPN或PNP型晶体管或二极管,是微控制器,微处理器或FPGA的组成部分。
远程精度为±1 °C适用于多个设备制造商,无需校准。双线串行接口接受SMBus写字节,读字节,发送字节和接收字节命令,以设置报警阈值和读取温度数据。
TMP411器件中包含的功能包括:串联电阻取消,可编程非理想因子,可编程分辨率,可编程阈值限制,用户定义的偏移寄存器,用于最大精度,最小和最大温度监视器,宽远程温度测量范围(高达150°C),二极管故障检测和温度警报功能。
TMP411器件采用VSSOP-8和SOIC-8封装。
