Allegro MicroSystems Inc. High Accuracy Hall-Effect Current Sensor With 265 Μω Integrated Conductor ACS724LMCTR-65AB-T

The ACS724LMC series is a high-accuracy, Hall-effect-based current sensor with a 265 µΩ integrated conductor for AC or DC current sensing in industrial and communication systems. It operates from a single 3.3 V or 5 V supply, provides a ratiometric output, and is housed in a custom 16-pin SOICW package with 8.7 mm creepage and clearance, 2.5× thicker leads, and a body sized for reinforced isolation. The device is AEC-Q100 automotive qualified and certified to UL60950-1 and UL62368-1 with a 5 kV RMS withstand voltage, 1140 V RMS basic isolation working voltage, and 757 V RMS reinforced isolation working voltage. It features differential Hall sensing for common-mode field rejection, chopper-stabilized output for temperature stability, and a filter pin for bandwidth optimization. The ACS724LMCTR-65AB-T variant has a full-scale range of ±65 A and a sensitivity of 30.75 mV/A.
