illustrate

LM82是一个2线串行接口的数字温度传感器,感应电压和数字超温探测器使用一个Delta - Sigma模拟到数字转换器的远程二极管的温度。 LM82准确地检测自身的温度以及外部设备的温度,如奔腾II ™ 处理器或连接2N3904系列二极管。 使用LM82只要一个专用的二极管(半导体结)是可用的芯片上可以检测到任何ASIC的温度。 使用SMBus接口的主机可以在任何时候访问LM82的寄存器。 ^ T_CRIT_A输出激活时,任何温度比一个可编程的比较器的限制,T_CRIT更大。 一个^ INT输出的激活时,会发生任何温度比其相应的可编程比较高限更大的。

主机方案,以及回读的T_CRIT寄存器状态和2 T_HIGH寄存器。 三态逻辑输入,允许两个引脚(ADD0 ADD1)选择9的LM82的SMBus地址。 T_CRIT和所有T_HIGHs在127 ° C的默认阈值传感器的权力。 LM82是引脚引脚和寄存器兼容与LM84,Maxim的MAX1617和ADM1021 ADI公司。
