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 magnetic cores or shields, making it ideal for applications requiring the measurement of hundreds or thousands of amperes flowing through busbars or PCB traces. The device features differential Hall sensing for common-mode field rejection, a wide sensing range, and high isolation. It offers user-programmable overcurrent and overtemperature fault detection, along with built-in diagnostics. The ACS37610 is available in regular and low-power modes to optimize SNR and power consumption, and is AEC-Q100 Grade 0 automotive qualified.
