ACS37002 Description
The ACS37002 is a fully integrated Hall-effect current sensor in an SOICW-16 package that is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming. The current is sensed differentially by two Hall plates that subtract out interfering external monmode magnetic fields. The package construction provides high isolation by magnetically coupling the field...
