DALLAS, Oct. 12, 2021 /PRNewswire/ -- Texas
Instruments (TI) (Nasdaq: TXN) today introduced the industry's most
accurate 3D Hall-effect position sensor. With the TMAG5170,
engineers can achieve uncalibrated ultra-high precision at speeds
up to 20 kSPS for faster and more accurate real-time control in
factory automation and motor-drive applications. The sensor also
provides integrated functions and diagnostics to maximize design
flexibility and system safety, while using at least 70% less power
than comparable devices. The TMAG5170 is the first device in a new
family of 3D Hall-effect position sensors that will meet a wide
range of industrial needs – from ultra-high performance to general
purpose. For more information, see www.ti.com/tmag5170-pr.
"Smart factories have an increasing number of highly automated
systems that must operate in a more integrated manufacturing flow
while simultaneously collecting data to control processes," said
Noman Akhtar, senior research
analyst, Omdia. "3D position-sensing technology that delivers
higher accuracy, speed and power efficiency is essential for
automated equipment to quickly deliver precise real-time control
for increased system efficiency and performance while reducing
downtime."
Achieve faster, more accurate real-time control
The TMAG5170 is the industry's first 3D Hall-effect position
sensor to provide a low 2.6% full-scale total error at room
temperature. It also features best-in-class drift of 3% total error
– 30% lower than the next closest competitor – along with at least
35% lower error than comparable devices in the presence of a
cross-axis field. Together, these features enable the TMAG5170 to
deliver higher accuracy than any other 3D Hall-effect position
sensor, eliminating the need for end-of-line calibration and
off-chip error compensation, and simplifying system design and
manufacturing. To achieve faster, more accurate real-time control,
the sensor supports measurements as high as 20 kSPS for low-latency
throughput of high-speed mechanical motion.

real-time control in the technical article, "How to enable
real-time control in your automated industrial system with
high-precision sensors."
Maximize design flexibility and system safety with integrated
functions and diagnostics
The TMAG5170 eliminates the need for off-chip computation and
enables flexible sensor and magnet orientations by integrating
features such as an angle calculation engine, measurement
averaging, and gain and offset compensation. These features
simplify design and maximize system flexibility, enabling faster
control loops, reduced system latency and simpler software
development – regardless of sensor placement. The sensor's
integrated computation functions also reduce the system's processor
load by as much as 25%, enabling engineers to use general-purpose
microcontrollers (MCUs) such as TI's low-power MSP430™ MCUs to
minimize overall system cost.
Additionally, the TMAG5170 increases safety with a unique set of
smart diagnostic capabilities – such as checks for communication,
continuity and internal signal path – as well as configurable
diagnostics for the external power supply, magnetic field and
system temperature. This allows engineers to customize a safety
scheme at both the chip and system level for long-term reliability
and lower design costs.
Increase power efficiency by at least 70%
The TMAG5170 provides multiple operation modes to reduce power
consumption by at least 70% compared to other linear 3D Hall-effect
position sensors while maintaining system performance. These
configurable modes enable engineers to optimize power across a
1-SPS to 20-kSPS sampling range for battery-powered devices or
light-duty modes where system efficiency is paramount.
Package, availability and pricing
The TMAG5170 is available now from TI.com in an eight-pin,
4.9-mm-by-3-mm very thin shrink small-outline package (VSSOP).
Pricing starts at US$1.139 in
1,000-unit quantities. Multiple payment and shipping options are
available on TI.com.
