  • The Hall-effect current sensor with the least drift simplifies design processes in high-voltage systems.
  • The EZShunt integrated shunt collection streamlines designs, curtails system expenses, and boosts performance.

Texas Instruments (TI) has introduced its latest TTMCS1123 hall-effect current sensors, aiming to streamline design processes and enhance precision for engineers. These sensors are crafted for versatility, accommodating a wide spectrum of common-mode voltages and temperature variations. The lineup features an advanced hall-effect current sensor with minimal drift for high-voltage systems. Moreover, the collection includes current shunt monitors that negate the necessity for external shunt resistors in non-isolated voltage tracks. The accompanying evaluation module (EVM) enables users to channel the peak operating current via the hall input side and simultaneously assess the isolated output through a fortified isolation barrier.

Designed to accommodate a wide array of common-mode voltages and temperatures, the new offerings feature a hall-effect current sensor with the least drift optimised for high-voltage systems. Additionally, they present a collection of current shunt monitors, making external shunt resistors redundant for non-isolated voltage lines. A few characteristics of advanced sensors are:

  • Enhances design efficiency and precision in high-voltage operations.
  • Boasts reinforced isolation with an operational voltage of  ±1100-V.
  • Accuracy throughout its lifespan and across different temperatures.
  • Most compact integrated current shunt monitor.
  • Isolation – Exhibits a minimal sensitivity error of ±0.75%.
  • Has a 50 ppm/°C drift over temperature.
  • A ±0.5% drift over its lifetime.

 When selecting a current-sensing solution, design engineers often juggle cost, size, accuracy, and speed considerations. These latest products underscore how our expansive sensing technologies cater to these design dilemmas across diverse systems. The sensor’s exceptional precision, coupled with its minimal propagation delay, empowers designers to integrate them into high-voltage systems, a feat previously unattainable. This newfound capability paves the way for diminishing both system expenses and dimensions. The company claims that to maximise precision in high-voltage systems, consider utilising Hall-effect current sensors.
