Current Sensors Procurement Notes

Verify the specific suffix AB-T against the official datasheet to confirm pinout and electrical characteristics. Ensure the component meets AEC-Q100 requirements for your target application. Check for any recent Product Change Notifications regarding packaging or process updates. Confirm compatibility with your PCB footprint and thermal management strategy before finalizing procurement.

Current Sensors Selection Notes

Select this model when a 100 A current rating is required for bidirectional sensing. Consider the SOICW-16 package size for space-constrained designs. Evaluate the 4.5 V to 5.5 V supply requirement against your system power rails. The automotive grade qualification makes it suitable for harsh environment applications where standard industrial sensors may not suffice.

Current Sensors Part Context

This part belongs to the ACS724 series, which offers various current ratings including 30 A, 50 A, 65 A, and 100 A options. The series is characterized by its high accuracy and common-mode field rejection capabilities. The LMATR suffix indicates a specific tape-and-reel packaging format optimized for automated assembly processes in manufacturing environments.

Current Sensors Replacement Considerations

Direct substitutes include other variants within the ACS724 family such as ACS724LMATR-65AB-T or ACS724LMATR-50AB-T if lower current ratings are acceptable. Verify that any replacement maintains the same SOICW-16 package and electrical interface specifications.
