SBOS835B – MAY 2017 – REVISED AUGUST 2017 TMP464 High-Accuracy 5-Channel (4-Remote and 1-Local) Temperature Sensor
1 Features 3 Description The TMP464 device is a high-accuracy, low-power
temperature sensor using a two-wire, SMBus or I2C
compatible interface. Up to four remote diodeconnected temperature zones can be monitored
simultaneously in addition to the local temperature.
Aggregating the temperature measurements across a
system allows improved performance through tighter
guard bands and can reduce board complexity. A
typical use case is for monitoring the temperature
across different processors, such as MCUs, GPUs,
and FPGAs in complex systems such as servers and
telecommunications equipment. Advanced features
such as series resistance cancellation, programmable
non-ideality factor, programmable offset, and
programmable temperature limits are included to
provide a robust thermal monitoring solution with
improved accuracy and noise immunity. 1 4-Channel Remote Diode Temperature Sensor …
