The design supports efficient power conversion, minimizing heat generation. 2. 8682L IC Pinout Configuration
The OZ8682L incorporates numerous advanced features that make it suitable for power‑sensitive portable designs. The following table summarises its most important attributes:
: Frequently replaced on MacBook Pro logic boards (like the 820-2879-B ) when the device fails to charge or does not recognize the battery.
For design engineers, the OZ8682L offers programmable voltage and current limits, dual high‑side current sensing, and simplified SMBus control. For repair technicians, understanding the IC’s role in laptop charging circuits, its typical external components, and common failure modes is essential for effective troubleshooting. 8682l ic datasheet
While the official pinout diagram is not publicly available, typical SMBus battery charger ICs like the OZ8682L include the following functional pins:
Check the continuity between the main power adapter rail and the battery charging rail. A punctured MOSFET can bypass the 8682L control, feeding raw input voltage straight to the battery pack—a condition normally intercepted by the IC's over-voltage safety blocks.
Optimized for charging Li-ion battery packs, regulating both voltage and current to maximize battery lifespan. While the official pinout diagram is not publicly
The is frequently mentioned as a possible alternative to the OZ8682L. However, compatibility is not guaranteed. Repair technicians have noted that the OZ8681L may have different internal configurations, and direct substitution can lead to unexpected behaviour.
