Texas Instruments TMP468 고정확도 온도 센서
Texas Instruments TMP468 고정확도 온도 센서는 다중 영역의 고정확도, 저전력 온도 센서입니다. 이 센서는 2선, SMBus 또는 I2C 호환 인터페이스를 사용합니다. 국부 온도 외에도 원격 다이오드에 연결된 최대 8개의 온도 영역을 동시에 모니터링할 수 있습니다.
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.
