SE95DP: 超高准确度数字温度传感器与温度监控器

SE95是一款温度-数字转换器,采用片内集成带隙温度传感器和Σ-Δ型模数转换技术制造。该器件还是一个热检测器,具有过温检测输出。

SE95集成一系列数据寄存器,可通过双线式串行I²C总线接口从控制器访问:

该器件提供开漏输出(针脚OS),可在温度超过编程限值时激活。具有三个可选逻辑地址针脚(针脚A2至A0),因此一条总线上可以连接8个器件,不会产生地址冲突。

SE95可针对不同工作条件进行配置。可将其设为正常工作模式以便周期性监控环境温度,或者设为关断模式以便最大程度降低功耗。OS输出可在两种可选模式中的任意一种下工作:OS比较器模式和OS中断模式。它的激活状态可选为高电平或低电平。可对定义连续故障数量以激活OS输出的故障队列进行编程,也可对设定点限值进行编程。

温度寄存器始终存储13位二进制补码数据,温度分辨率为0.03125 ℃。对于精确测量热漂移或热逃逸的应用,这一较高的温度分辨率尤其有用。为了正常工作并与LM75A兼容,仅读取11 MSB,分辨率为0.125 ℃,以便提供额定精度。为了与LM75兼容,仅读取9 MSB。

上电后,该器件进入正常工作模式,OS进入比较器模式,温度阈值为80 ℃,迟滞为75 ℃,因此可用作带有预定义温度设定点的独立恒温器。转换速率可以编程设置,默认值为每秒10次转换。
