3 Description
The TMP4718 is a high accuracy 1°C temperature
sensor with one local integrated sensor and a remote
temperature sensor input that can be connected to
a diode-connected transistor, such as the popular
MMBT3904 NPN transistor, to replace traditional
thermistors or thermocouples. The remote input
can also be connected to a substrate thermal
transistor or diode integrated inside microprocessors,
microcontrollers, or FPGAs to monitor the die
temperature of the IC.
The TMP4718 supports I2C and SMBus
communication, with 1.2-V logic compatible inputs
that support 0.8-V thresholds regardless of the main
supply. The TMP4718 includes the Series Resistance
Cancellation feature to automatically eliminate
temperature errors caused by series resistance of
up to 1 kΩ, allowing for greater flexibility routing
to thermal diodes. The programmable offset feature
allows the device to report adjusted offset-adjusted
temperature data based on pre-calibrated data in
specific user environments. Measurements can be
done automatically with programmable conversion
period, or with one-shot conversion triggered by an
I2C command.
The TMP4718A and TMP4718B offer the same
function but different SMBus or I2C device addresses.
This allows the system to support more than two
sensors on the same bus.
