　　the allegro acs37610 current sensor ic enables low-cost solutions for ac and dc current sensing without the need for an external field concentrator core or a u-shaped magnetic shield. it is designed for applications where hundreds or thousands of amperes flow through a busbar or pcb.

　　current flowing through a busbar or pcb trace generates a magnetic field that is sensed by the monolithic, low-offset, linear hall ic. the differential sensing topology virtually eliminates all types of error caused by common-mode stray magnetic fields. the wide spacing between the differential hall elements (2.58 mm) coupled with the increased sensitivity of each hall element enable the acs37610 to achieve a superior signal-to-noise ratio (snr) and improved resolution. while not mandatory, a notch or slit in the current-carrying busbar or pcb copper trace provides further improvements to system snr. high isolation is achieved via

　　the no-contact nature of this simple assembly.

　　the acs37610 is offered with regular and low-power mode, enabling customers to achieve optimal snr and power consumption. a dedicated user-programmable overcurrent and overtemperature fault pin and a slew of built-in diagnostics, including broken-ground and vcc detection, make it ideal
