Texas Instruments TMP468高精度温度センサ
Texas Instruments TMP468高精度温度センサは、マルチゾーン、高精度、低消費電力の温度センサです。このセンサは、2線式のSMBusまたはI2C互換インターフェイスを使用します。ローカルの温度に加えて、最大8つのリモートダイオード接続の温度ゾーンを同時に監視できます。
Aggregating the temperature measurements across a system allows improved performance through tighter guard bands and reduces board complexity. A typical use case is for monitoring the temperature across different processors like MCUs, GPUs, and FPGAs in complex systems.
These systems include servers and telecommunications equipment. Advanced features like series resistance cancellation, programmable non-ideality factor, programmable offset, and programmable temperature limits are included in the Texas Instruments TMP468 to provide a robust thermal monitoring solution with improved accuracy and noise immunity.
