Texas Instruments TMCS1123/TMCS1123-Q1 Hall-Effect Current Sensors
Texas Instruments TMCS1123/TMCS1123-Q1 Precision Hall-Effect Current Sensors are designed to address the need for highly accurate current measurements in high-voltage systems such as electric vehicle (EV) charging and solar energy. These galvanically isolated sensors offer up to 80ARMS at +25°C and robust reinforced isolation with 1100VDC reinforced working voltage and 5000VRMS withstand isolation voltage. The precision signal conditioning circuitry with built-in drift compensation achieves less than 1.75% maximum total error over temperature and lifetime with no system-level calibration, making the TMCS1123/TMCS1123-Q1 series a highly accurate solution throughout the system's lifetime. The devices can be used for AC and DC current measurements and offer a bandwidth of 250kHz. TI TMCS1123/TMCS1123-Q1 Precision Hall-Effect Current Sensors operate with a low voltage supply from 3V to 5.5V and come in an SOIC (DVG) 10-pin package. The TMCS1123-Q1 devices are AEC-Q100 qualified for automotive applications.Features
