8682l Datasheet -
For modern technicians, understanding this chip is key to successfully repairing a range of legacy and current laptop models. While the original manufacturer datasheet may be elusive, the information compiled here from O2Micro's official press releases and component distributors provides the essential knowledge required for identification, sourcing, and expert-level handling of this critical power management IC.
): Typically rated around , allowing it to handle standard DC-DC conversion tasks. Continuous Drain Current ( IDcap I sub cap D
Primary DC voltage input drawn directly from the laptop AC adapter line or peripheral DC source.
The backbone of the 8682L's adaptability is its . This communication protocol follows the Smart Battery Charger Specification, allowing it to function as a slave device managed by the system's embedded controller (EC), or safely interact directly with the smart battery’s integrated fuel gauge. Through the SDA (Serial Data) and SCL (Serial Clock) lines, the host system writes parameters into internal registers to define: Max Charge Voltage limits Max Charge Current rates Critical Trip Points for temperature and overcurrent Multi-Chemistry Compatibility 8682l Datasheet
Cycle-by-cycle overcurrent protection, overvoltage protection, adapter current limiting, input undervoltage lockout (UVLO), and thermal shutdown tracking. Pinout Configuration
: Low-Side and High-Side Gate Drive outputs. These output lines switch external N-channel MOSFETs on and off to execute synchronous step-down voltage conversion.
