The ACS37612 is a coreless, Hall-effect current sensor IC designed for contactless, non-invasive AC and DC current sensing in applications such as busbars or PCB traces, with a bandwidth of 120 kHz and a TSSOP8 surface mount package. It operates from a 5 V single supply, provides a ratiometric output in bidirectional mode, and has a differential magnetic sensitivity of 10 mV/G. The device is AEC-Q100 Grade 0 qualified, supports an ambient temperature range of -40°C to 150°C, and features factory-programmed temperature compensation with typical sensitivity error of ±1% and quiescent output offset error of ±3 mV. Common-mode magnetic field rejection is enabled through differential Hall sensing.
The ACS37612 simplifies high-current sensing with its contactless, coreless design, offering high precision, common-mode field rejection, and a wide sensing range (200A to >1000A).
