Texas Instruments Unveils “Industry’s Most Accurate 3D Hall Effect Position Sensor” ”Dallas Breaks New Ground
Dallas-based Texas Instruments today introduced a new sensor that can help smart factories operate with more precise, real-time control.
TI claims that its new TMAG5170 “is the most accurate 3D Hall effect position sensor in the industry”. Engineers using it can achieve ultra-high precision at speeds of up to 20kSPS while using at least 70% less energy, according to the company.
The sensor also provides built-in functions and diagnostics to maximize design flexibility and system safety.
âSmart factories have a growing number of highly automated systems that need to operate in a more integrated manufacturing flow while simultaneously collecting data to control processes,â said Noman Akhtar, senior research analyst at Omdia, in a statement. â3D position sensing technology that delivers superior accuracy, speed and energy efficiency is essential for automated equipment to quickly provide precise real-time control for increased system efficiency and performance while reducing downtime. ‘stop. “
Part of a new family of TI sensors
The TMAG5170 is the first device in a new TI family of 3D Hall effect position sensors targeting a range of industrial needs, from ultra-high performance to general use, according to TI.
Crunch the numbers
TI claims that 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 has the best drift in its class of 3% total error, which is 30% lower than that of the next closest competitor, as well as at least 35% lower error than comparable devices in presence of a transversal field, according to the company. .
By providing greater accuracy, the new sensor eliminates the need for end-of-line calibration and off-chip error compensation, simplifying system design and manufacture.
Built-in sensor functions reduce system processor load by up to 25%, allowing engineers to use general-purpose microcontrollers (MCUs), which can help minimize overall system costs.
Intelligent diagnostic capabilities
Safety is another selling point of the new sensor. The TMAG5170 has a unique set of intelligent diagnostic capabilities, including internal communication, continuity and signal path checks, as well as configurable diagnostics for external power, magnetic field, and system temperature. . This allows for customized security schemes at both the chip and system level, which translates into long-term reliability and lower design costs, according to TI.
