Battery Chargers Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability is restricted to existing stock or obsolete channels. Engineers must confirm end-of-life status and transition plans immediately. Sourcing should focus on verified distributors holding legacy inventory. Design-in activities require immediate substitution analysis due to the permanent cessation of manufacturing support.

Battery Chargers Selection Notes

Selection requires evaluating compatibility with single-cell lithium chemistry requirements. The 1.5A current limit suits low-to-medium power portable applications. The 16-pin QFN footprint dictates specific PCB layout considerations for thermal dissipation. Designers must verify that the 6.25V input tolerance aligns with their adapter specifications. Integration of external components for current programming must follow official datasheet guidelines.
