The formula is:

The 8682L sits between low-cost TP4056 (larger package) and higher-performance MCP73831 (more expensive). The 8682L IC is a competent, low-cost linear charger for single-cell Li-ion batteries, especially in space-constrained portable devices. While finding a canonical 8682L IC datasheet can be challenging, the information compiled here—pinout, electrical specs, application circuit, and troubleshooting—provides a reliable foundation for most design and repair tasks. 8682l ic datasheet

Occasionally, the 8682L appears in an 8-pin package with additional pins for thermal pad (exposed pad for heat dissipation) and dual LED drive outputs. Always verify the top marking. | Parameter | Min | Typ | Max
