The OZ8682L, commonly marked 8682L, is a highly integrated SMBus-programmable multi-chemistry battery charge controller designed for portable power systems, notably laptop motherboards. Featuring a QFN-16 package, it manages power through hybrid boost functionality and operates within an industrial temperature range of -40°C to +85°C.

: The RT8239B is another high-efficiency, main power supply controller for notebooks. Information from repair communities (like BadCaps and ChinaFix ) and datasheet sites directly confirm that the UP1589Q and RT8239B are essentially the same device, meaning they are all likely cross-compatible with the OZ8682L.

Cross-referencing with major manufacturers (such as Seiko Instruments, Mitsumi, or Sanyo) suggests that the is often a positive voltage regulator with a fixed output voltage, typically in the range of 3.3V, 5V, or 8V, housed in a small SOT-23 or TO-92 package.

The OZ8682L relies on standard system management bus rules to exchange hardware telemetry with the host processor and smart battery pack. : SMBus Level 2 Compliant. Package Type : 16-pin QFN (Quad Flat No-leads).

This case study is a vital lesson: always perform comprehensive diagnostic steps before replacing the IC.
