Allegro MicroSystems Inc. Coreless, High Precision, Hall-Effect Current Sensor IC ACS37610LLUA-005B5

The ACS37610 is a coreless, high-precision Hall-effect current sensor IC designed for contactless AC and DC current sensing in applications with busbars or PCB traces carrying currents from 100 A to over 4000 A. It features differential Hall sensing to reject common-mode magnetic fields, a bandwidth of DC to 250 kHz, and a fast response time of less than 2 μs. The device operates from a single 3.3 V or 5 V supply, supports programmable offset and sensitivity trim, and includes integrated overcurrent and overtemperature fault detection. It is housed in an 8-pin TSSOP package (suffix -LU), measuring 3.1 mm × 3.1 mm × 1 mm, and is qualified to AEC-Q100 Grade 0 for automotive use. The ACS37610LLUA-005B5 variant is optimized for bidirectional sensing with a nominal sensitivity of 5 mV/G at 5 V supply.
