[{"type":"text","content":"• Lowest-drift isolated Hall-effect current sensor reduces design complexity in high-voltage systems\n • EZShunt™ integrated shunt portfolio simplifies designs while reducing system cost and maximizing performance\n\n\nDALLAS, Aug. 22, 2023 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN), a leader in advanced sensing technologies, today debuted new current sensors to help engineers simplify their designs while improving accuracy. Designed for a broad range of common-mode voltages and temperatures, the new products include a lowest-drift isolated Hall-effect current sensor for high-voltage systems and a portfolio of current shunt monitors that eliminate the need for an external shunt resistor for nonisolated voltage rails.\n\n \n \n \n \n \n \n\n \nThe new TMCS1123 Hall-effect current sensor offers design simplicity and accuracy for high-voltage systems, featuring the industry's highest reinforced isolation and highest accuracy over lifetime and temperature. For nonisolated systems up to 85 V and 75 ARMS, TI's new EZShunt™ portfolio includes the industry's smallest fully integrated current shunt monitor and the industry's highest-accuracy 75-A integrated shunt solution. For more information, see TI.com/TMCS1123 and TI.com/EZShunt.\n\"When choosing a current-sensing solution, design engineers weigh the trade-offs of four key factors: cost, size, accuracy and speed,\" said Jason Cole, business unit manager. \"These new products highlight how the breadth of our sensing technologies address this design challenge for a variety of systems. Take the TMCS1123, for example; its high accuracy and low propagation delay enable designers to now use Hall-effect sensors in high-voltage systems where they couldn't before – and that opens the door to reduce system cost and size.\"\nAchieve fast, accurate control in high-voltage systems with Hall-effect current sensorsThe need for highly accurate current measurements in high-voltage systems such as electric vehicle chargers and solar inverters is growing, but Hall-effect current sensors have typically been overlooked given their high drift over lifetime. The TMCS1123 Hall-effect current sensor features the highest reinforced isolation working voltage of 1,100 VDC. The TMCS1123 also features a maximum sensitivity error of ±0.75% with 50 ppm/°C drift over temperature and ±0.5% drift over lifeti...
