Procurement Notes
Verify the specific suffix SEWL against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with the intended PCB footprint for the 14-WFDFN enclosure. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this component when designing systems that require high accuracy in state-of-charge reporting for single-cell lithium batteries. The ModelGauge m5 EZ technology reduces the need for extensive user calibration compared to traditional coulomb counting methods. Consider the low operating current if extending battery life is a critical design constraint.
Part Context
This part belongs to the MAX17260 series, which utilizes Maxim Integrated's ModelGauge technology. The series is engineered to provide robust fuel gauging solutions for portable electronics. The SEWL suffix typically denotes a specific tape and reel packaging option for automated assembly processes within the broader MAX17260 product line.
