Engineers can achieve consistent, accurate measurements over time and temperature in high-voltage systems
DALLAS, July 7, 2020 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced the industry's first zero-drift Hall-effect current sensors. The TMCS1100 and TMCS1101 enable the lowest drift and highest accuracy over time and temperature while providing reliable 3-kVrms isolation, which is especially important for AC or DC high-voltage systems such as industrial motor drives, solar inverters, energy-storage equipment and power supplies. For more information, see www.ti.com/TMCS1100-pr and www.ti.com/TMCS1101-pr.
Ongoing demand for higher performance in industrial systems is driving the need for more precise current measurement, in addition to reliable operation, which often comes with the cost of increased board space or design complexity. TI has applied its expertise in both isolation and high-precision analog to the TMCS1100 and TMCS1101, enabling engineers to design systems that will provide consistent performance and diagnostics over a longer device lifetime, keeping its solution size compact without increasing design time.

Improve system performance with the lowest drift over time and temperatureThe zero-drift architecture and real-time sensitivity compensation of the TMCS1100 and TMCS1101 enable extremely high performance, even under operational conditions such as temperature changes and equipment aging. With an industry-leading total sensitivity drift over temperature of 0.45%, maximum, which is at least 200% lower than other magnetic current sensors, and a maximum full-scale offset drift of
