TI's "Zero Drift" Hall-Effect Current Sensor
This week, TI announced what they claim to be “the industry’s first zero-drift Hall-effect current sensors.” These new chips, the TMCS1100 and TMCS1101, are said to allow high performance, even under the influence of temperature change and equipment aging.
These claims are supported by a total maximum thermal drift of 0.45%, and a 0.5% lifetime sensitivity drift. TI claims that these figures are respectively 200% and 100% lower than other magnetic current sensors.
Doors Opened With Zero Drift
Today, there are many demands for current measurement devices to monitor and control electrical systems, hopefully, to prevent failures. Having more accurate open-loop sensors, like the new Texas Instruments Hall-effect current sensors, will make it possible to detect smaller levels of performance variation, allowing for a deeper understanding of system performance.
This news offers significant improvements in current sensing accuracy and will hopefully aid in better system performance, protection, and cost in the future.
