Product Overview
The Allegro ACS37610 is a coreless, high-precision Hall-effect current sensor IC designed for low-cost AC and DC current sensing solutions. It eliminates the need for external cores or magnetic shields, making it ideal for applications requiring measurement of hundreds or thousands of amperes through busbars or PCB traces. The device features differential Hall sensing for common-mode field rejection, high bandwidth (DC to 250 kHz), and a very fast response time (<2 s). It offers user-programmable overcurrent and overtemperature fault detection, along with built-in diagnostics. Available in a compact TSSOP-8 package, the ACS37610 supports 3.3V or 5V single supply operation and is AEC-Q100 Grade 0 automotive qualified.
