8682l Ic Datasheet «1080p»

(also referred to as ) is a highly integrated SMBus Level 2 Battery Charger controller manufactured by O2Micro International

1. Check LCSC or Mouser part numbers – Search “8682L” on LCSC.com; often a manufacturer (e.g., Lii Semiconductor, Microne, Nanjing Ebyte) is listed. Then search that manufacturer’s site.
2. Search by function – Use parameters: “linear Li-ion charger SOT-23-6 4.2V 500mA”. Alternatives with available datasheets include TP4054, MCP73831, STC4054, or YX8050. These are pin-compatible in most cases.
3. Look for “8682L” on Alibaba vendor listings – Some vendors upload the actual datasheet as an image or PDF. Cross-check the pinout.
4. Extract from open hardware designs – Search GitHub or Hackaday for “8682L” – community members often reverse-engineer and share.
5. Use a logic analyzer – If you have a physical IC, probe the PROG pin voltage, CHRG/STDBY behavior, and voltage at BAT during charge. Validate against this guide.

mm, which is ideal for the space-constrained environments of modern laptops. Primary Function: It acts as a DC/DC converter 8682l ic datasheet
