TMP63 100 k

Ω Linear Thermistor With Small 0402 Package

1

1 Features

1

•

Silicon-based thermistor with a

Positive Temperature Coefficient (PTC)

•

Linear resistance change across temperature

compared to non-linear thermistors

–

Simplifies resistance-to-temperature

conversion methods

–

Reduces look up table memory requirements

–

Eliminates the need for linearization circuitry or

multipoint calibration

–

Decreases the accuracy spread across a wide

temperature range

•

100-k

Ω nominal resistance at 25°C (R25)

•

Consistent sensitivity across temperature

–

6400 ppm/°C TCR (25°C)

–

0.2% typical TCR tolerance across

temperature (–40°C to 125°C)

•

Wide operating temperature:

–

–40°C to +125 °C

•

Fast thermal response time:

–

0.6 second for DEC package

•

Long lifetime and robust performance

–

Ultra-low power consumption compared to

traditional NTCs which minimizes errors

caused by self heating

–

Built-in fail-safe in case of short-circuit failures

–

<1% maximum drift after high temperature and

high humidity stress tests

•

Available package options:

–

X1SON (DEC/0402 footprint)

2 Applications

•

Temperature measurement and monitoring

•

Thermal compensation

•

Thermal protection (with comparator)

3 Description

The TMP63 small silicon linear thermistors are

designed for temperature measurement, protection,

compensation, and control systems. Compared to

traditional NTC thermistors, the TMP63 device offers

enhanced linearity and consistent sensitivity across

the full temperature range.

The TMP63 offers robust performance due to device

immunity to environmental variation and built-in fail-

safe behaviors at high temperatures. This device is

currently available in a 2-pin, surface-mount, 0402

footprint-compatible X1SON package.
