Product Overview
The TMP63 is a Texas Instruments 100-kΩ linear PTC thermistor categorized as a Sensor. The device uses a silicon-based thermistor structure with a positive temperature coefficient, providing a resistance output that is specified around a nominal 100 kΩ at 25°C.
Electrical limits include a recommended voltage range of 0 V to 5.5 V across pins 2 (+) and 1 (-), and recommended sensing current from 0 µA to 40 µA. Absolute maximum ratings specify 6 V maximum across the device and 450 µA maximum current through the device.
Package options are X1SON/DEC 2-pin 0.60 mm × 1.00 mm and SOT-5X3/DYA 2-pin 0.80 mm × 1.20 mm. The DEC package supports -40°C to 125°C operating free-air temperature, while the DYA package supports -40°C to 150°C. Pin 1 is the thermistor negative terminal, and pin 2 is the positive terminal that should be at higher voltage potential than pin 1.
