The STTS751 is a digital temperature sensor which communicates over a 2-wire SMBus 2.0 compatible bus. The temperature is measured with a user-configurable resolution between 9 and 12 bits. At 9 bits, the smallest step size is 0.5 °C, and at 12 bits, it is 0.0625 °C. At the default resolution (10 bits, 0.25 °C/LSB), the conversion time is nominally 21 milliseconds.

The open-drain EVENToutput is used to indicate an alarm condition in which the measured temperature has exceeded the user-programmed high limit or fallen below the low limit. When the EVENTpin is asserted, the host can respond using the SMBus Alert Response Address (ARA) protocol to which the STTS751 will respond by sending its slave address.

The STTS751 is a 6-pin device that supports user-configurable slave addresses. Via the pull-up resistor on the Addr/Thermpin, one of four different slave addresses can be specified. Two order numbers (STTS751-0 and STTS751-1) provide two different sets of slave addresses bringing the total available to eight. Thus, up to eight devices can share the same 2-wire SMBus without ambiguity, thereby allowing monitoring of multiple temperature zones in an application.

The two-wire interface can support transfer rates up to 400 kHz. Two small footprint packages are available: a UDFN-6L and a standard SOT23-6L package.

stts751是数字温度传感器连通在一个2线SMBus兼容2总线。温度测量与用户可配置的分辨率为9和12位。在9位，最小步长为0.5°C，并在12位，这是0.0625°在默认的分辨率（10位、0.25°C / LSB），转换时间名义上是21毫秒。

开漏eventoutput用于指示报警状态，测量的温度超过上限或低于设定的低限的用户。当eventpin断言，主机可以使用SMBus报警响应地址（ARA）协议的stts751就会从地址发送。

stts751是支持用户可配置的从机地址6针装置。通过对地址/ thermpin上拉电阻，四个不同的从机地址可以指定。二阶数（stts751-0和stts751-1）提供两套不同的从机地址总数有八。因此，多达八个设备可以共享相同的2线SMBus没有歧义，从而允许在应用程序中的多个温度区监测。

两线接口可以支持传输速率高达400千赫。两小体积封装可供选择：一udfn-6l和标准SOT23-6L封装。
