DALLAS, Feb. 17, 2020 /PRNewswire/ -- Texas Instruments
(TI) (Nasdaq: TXN) today expanded its temperature sensing portfolio
to include linear thermistors that deliver up to 50% higher
accuracy than negative temperature coefficient (NTC) thermistors.
The higher accuracy of TI's thermistors enables operation closer to
the thermal limits of the other components and the overall system,
helping engineers maximize performance while reducing
bill-of-materials (BOM) and total solution cost. For more
information, see www.ti.com/thermistors-pr.
NTC thermistors are widely used due to their low price; however,
they present several challenges to design engineers, including
degraded performance at temperature extremes and complex
calibration requirements, which increases design time. TI's new
linear thermistors are available at a similar price while providing
significantly more value – most notably minimizing design time,
reducing component count and increasing system performance.
Extend system performance and reliability
TI's new thermistors deliver reliable, highly accurate thermal
measurements, particularly at temperatures above 80°C. This is
especially important for industrial, automotive and consumer
applications where precise, real-time temperature readings are
fundamental to system performance and protection. To learn more
about the differences between NTCs and TI's linear thermistors,
read the white paper, "Temperature sensing with thermistors."
NTC thermistors provide less accurate temperature readings due
to their low sensitivity and high resistance tolerance at
temperature extremes. To compensate for these challenges, many
engineers calibrate at three points across the temperature range or
use multiple thermistors to monitor different temperature ranges.
These approaches can still produce unreliable temperature readings,
which can require systems to shut down before reaching their true
thermal limit. The linearity and high accuracy of TI's thermistors
enable single-point calibration, which maximizes system performance
and simplifies design.
TI's thermistors also offer very low typical drift of 0.5% to
improve the reliability of temperature measurements, enabling
designers to boost system performance while maintaining safe
operation. Engineers can use TI's thermistor design tool, available
on the thermistor product pages and data sheets on TI.com, to
quickly and easily calculate temperature resistance values and
kick-start their design with example conversion methods and
code.
Reduce system cost and size
By eliminating the need for additional linearization circuitry or
redundant NTC thermistors, TI's thermistors help engineers simplify
design, lower system cost and reduce printed circuit board (PCB)
layout size by at least 33%, compared to NTC thermistors. In
addition, TI's thermistors are one-tenth the size of similar
silicon-based linear thermistors, with a low profile and small
package area that enable placement closer to thermal hot spots for
faster thermal response and more consistent temperature
measurements.
Package, availability and pricing
TI's new thermistor portfolio, which includes the TMP61, TMP63 and
TMP64, is available now through TI and authorized distributors with
starting prices as low as US$0.05 in
1,000-unit quantities. The devices are offered in through-hole
packaging and surface-mount 0402 and 0603 footprint options.
