NE1617ADS: 用于微处理器系统的温度监控器

NE1617A是一款精确的双通道温度监控器。该器件可测量自身温度,以及远程传感器的温度。远程传感器是一个连接二极管的晶体管。它可以是分立式NPN/PNP(如2N3904/2N3906),也可以是内置在另一个芯片中并且连接二极管的PNP(如某些Intel微处理器)。

远程和本地传感器的温度数据存储在寄存器中,可通过双线式SMBus读取。温度数据的更新速率可以通过SMBus进行编程(平均电源电流取决于更新速率——速率越高,电流越大)。

除了以编程速率更新温度数据的正常工作模式,另外还有可以强迫更新温度数据的单次模式。

此外,还提供警报功能,可感测过温或欠温条件。该警报的跳变点同样可以进行编程。

该器件可以采用九个地址中的一个(由两个地址针脚确定),因此SMBus上最多可连接九个NE1617A器件。

还能将其置于待机模式下(以便节能)。可以通过软件(通过SMBus)或硬件(通过STBY针脚)实现。
