Procurement Notes
Verify product status carefully as the XRP6840 series is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors only, as standard stock may be limited or unavailable. Ensure compatibility with existing system designs before procurement due to potential end-of-life constraints.
Selection Notes
Select this component for applications requiring integrated supercapacitor charging and high-current LED driving in a compact form factor. The TQFN-20 package suits space-constrained designs. Verify that the 2.7 V to 5.5 V input range aligns with the system power supply. Consider the obsolete status when planning long-term production cycles.
Part Context
The XRP6840AILB-F belongs to the XRP6840 series from MaxLinear, which focuses on LED lighting drivers and power management ICs. This specific variant is part of a family designed for flash LED applications, often paired with evaluation boards like the XRP6840EVB for development purposes. The series emphasizes integration of charging and driving functions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The XRP6840BILB-F and XRP6840AILBTR-F are related variants within the same series but require verification of pinout and electrical specifications for direct replacement.
