• On-board charging (OBC) units in electric vehicles

Current Sensors Procurement Notes

Verify the specific suffix 'KLATR' against the manufacturer's latest datasheet to confirm package type and tape-and-reel specifications. Confirm that the 4.75V–5.25V supply requirement aligns with system design constraints. Check for any recent Product Change Notifications (PCN) regarding packaging or manufacturing site transitions. Ensure compatibility with AEC-Q100 requirements if deploying in automotive environments.

Current Sensors Selection Notes

Select this component when differential output signals are required to minimize common-mode noise interference in high-noise industrial or automotive settings. The 20A rating suits moderate-power motor drives and power converters. Consider the 16-SOIC footprint for PCB layout space. Note that the narrow supply voltage window (4.75V–5.25V) necessitates stable power regulation compared to wider-range sensors.

Current Sensors Part Context

This part belongs to the ACS73x family of high-precision, galvanically isolated current sensors designed for demanding applications. Unlike single-ended output variants, the KLATR suffix indicates a differential output architecture, offering superior performance in electrically noisy environments. It complements other ACS73x models by providing automotive-grade durability combined with high-bandwidth signal fidelity.

Current Sensors Replacement Considerations

ACS732KLATR-40AB-T offers identical differential output and package but with a 40A rating. ACS732KLCTR-20AB-T provides single-ended output instead of differential. Verify pinout and sensitivity changes when substituting.
