Texas Devices wins Better of Sensors 2020 Award for its TMCS1100 and TMCS1101 zero-drift Corridor-effect present sensors

Texas Instruments wins Best of Sensors 2020 Award for its TMCS1100 and TMCS1101 zero-drift Hall-effect current sensors

Texas Instruments was named the Most Innovative Product Winner in the Industry category of the Best of Sensors Awards 2020 for its TMCS1100 and TMCS1101 Zero Drift Hall Effect Current Sensors. Entries were judged and winners selected on the basis of market value, uniqueness of design and impact (ie the “size” of the problems solved or the issues raised).

Texas Instruments Incorporated (TI) is an American technology company headquartered in Dallas, Texas that develops, manufactures and sells semiconductors and various integrated circuits to electronics designers and manufacturers worldwide. TI is one of the world’s top ten semiconductor companies in terms of sales volume. The company’s focus is on the development of analog chips and embedded processors. The company also manufactures products for TI’s digital light processing technology and educational technology, including calculators, microcontrollers and multi-core processors. Known as a technology innovator, the company held 45,000 patents worldwide as of 2016.

A key feature of today’s world is the use of sensor technology. From giant buildings like smart buildings to self-driving cars to the smallest of portable devices, systems make real-time decisions based on their perception. System developers can use TI’s innovative sensors to accurately transfer information from the physical to the digital world, enabling intelligent autonomy.

A Hall effect sensor (or simply a Hall sensor) is a device that can be used to measure the strength of a magnetic field. The output voltage of a Hall-effect sensor is directly proportional to the magnetic field strength passing through it. Hall effect sensors are used for a variety of applications in the areas of proximity detection, positioning, speed detection, and current detection.

The continuing demand for higher performance in industrial systems requires more precise current measurement while maintaining reliable operation. Unfortunately, these attributes are often associated with the cost of increased board space and / or design complexity. TI used its expertise in isolation and high-precision analog to develop the TMCS1100 and TMCS1101 Hall-effect sensors. This enables engineers to design systems that provide consistent performance and diagnostics over the longer life of the equipment and keep the solution size compact without increasing design time.

With the TMCS1100 and TMCS1101, TI introduced the industry’s first zero-drift Hall-effect current sensors. These devices enable the lowest drift and the highest accuracy over time and temperature and at the same time offer reliable 3 kVrms isolation. This is especially important for AC or DC high voltage systems such as industrial motor drives, solar inverters, energy storage devices and power supplies.

The zero-drift architecture and real-time sensitivity compensation of the TMCS1100 and TMCS1101 enable extremely high performance, even under operating conditions such as temperature changes and aging of the devices. With an industry leading overall sensitivity drift over temperature of 0.45% or less, which is at least 200% lower than other magnetic current sensors, and a maximum full-scale offset drift of <0.1%, these devices provide the highest level of measurement accuracy and reliability over a wide current range. In addition, a 0.5% lifetime drift in sensitivity, at least 100% less than other magnetic current sensors, significantly reduces the performance degradation associated with system aging over time.

“Current meters play a critical role in monitoring electrical systems, including industrial motor drives, energy storage devices, and power supplies – where performance is everything today. However, these gauges are prone to thermal drift – something that engineers need to consider and correct in their designs. The announcement of TI’s industry-first zero-drift Hall-effect current sensors is significant in that the devices provide unparalleled measurement accuracy and a reduction in performance degradation over time, simplify the overall design, and result in better overall system performance, “said Judge Karen Field, Content Director for FierceElectronics.
