8682l Datasheet !!top!! Jun 2026
The "8682l" written in text is often not the actual on the component. SMD (Surface Mount Device) packages use short codes. For a device that is functionally an 8682l, the top may show:
✅ It dynamically balances energy demands between external power adapters and internal Li-ion battery arrays to prevent system brownouts during peak power events.
: A critical feature for industrial environments, ensuring the system maintains accuracy despite electromagnetic interference.
The outlines the specifications for the OZ8682L (also variants like OZ8682LN) , a highly integrated, multi-chemistry SMBus Level 2 battery charger controller primarily engineered for laptop motherboards and portable computer systems. Developed to handle advanced power management workloads, this integrated circuit (IC) functions as a synchronous buck converter that enables smart communication between the system board and intelligent battery packs. Core Technical Specifications
Low-side synchronous rectifying gate driver line. 8682l Datasheet
: A standout feature of this IC is its ability to provide a "Hybrid Power Boost." This allows the system to draw power simultaneously from both the battery and the AC adapter during periods of high demand (peak loads), preventing system throttles or crashes. Laptop Power Management
: The laptop fails to identify the AC adapter, refuses to charge a known-good battery, or drops power abruptly when the charger is unplugged.
The 8682L chip manages safe power distribution between an external DC adapter, the internal system rail, and the Lithium-Ion (Li-Ion) battery pack. : O2Micro (Optimized To Allow Innovation) Package Type : QFN-16 (Quad Flat No-leads, 16-pin variant)
The OZ8682L is a common component in laptop motherboards and is often sought by engineers for repairs in models like the or HP EliteBook series. It is also found in specialized Apple Macbook Pro and "Core Duo" 13" motherboards (specifically associated with part numbers like 820-1889-A and 820-2849-A) as a critical controller IC. The "8682l" written in text is often not
: Current sense inputs monitoring the voltage drop across an external power-resistor to calculate total system current draw. 2. The SMBus Communication Subsystem
: System Management Bus clock and data routing pins linked directly to the main SMBus topology.
Open-drain output signaling whether the adapter voltage is valid and safe for use. Exposed Pad Thermal Pad
: Differential current sense input pins placed across the output path to measure real-time current feeding directly into the cell configuration. : A critical feature for industrial environments, ensuring
: Laptop battery charging, DC/DC conversion, and system power path selection
