8682l Ic Datasheet Jun 2026

He pointed his microscope at a tiny, black, eight-legged chip near the power regulator. The markings were faded, scratched away by decades of thermal cycling. All that remained was a faint laser-etch: .

The (full part number OZ8682LN ) is a high-performance SMBus Level 2 Battery Charger IC manufactured by O2Micro . It is most commonly found in laptop power management circuits, specifically within Apple MacBook Pro models (e.g., A1278 and A1229) and other portable electronics. Core Specifications & Function

This exceeds the 125°C maximum junction temperature, so a heatsink or copper plane is mandatory for full load. The datasheet recommends derating above 700mA for ambient temperatures >50°C.

Multi-cell Lithium-Ion (Li-Ion) / Lithium-Polymer (Li-Po) battery charging

The is typically a single-cell lithium-ion battery charger IC and power path management device. It is commonly found in: 8682l ic datasheet

⚠️ Without the original datasheet, these pinouts are derived from common LDO topologies. Always test continuity and voltage behavior on a known working board or use a component tester.

The 8682L is a reliable choice for engineers seeking a compact, SMBus-controlled charging solution. It balances high integration with robust safety features, though it requires careful PCB layout (specifically regarding thermal dissipation and signal integrity for the SMBus lines) to achieve peak performance.

When working with the 8682L IC for repairs or new designs, keep the following in mind: He pointed his microscope at a tiny, black,

Proactively verify component datasheets from authoritative manufacturers or trusted trade databases like O2Micro's Product Portfolio Archive to secure authentic pin layouts before modifying system hardware.

The physical layout uses a space-saving . This package relies on a large under-chip exposed pad to dissipate thermal energy directly into the PCB's ground planes.

Even with a correct circuit, problems arise. Here’s a diagnostic table:

Lower gate drive output tied to the low-side synchronous N-channel rectifier MOSFET. PGND The (full part number OZ8682LN ) is a

and SMPS (Switch Mode Power Supply) driver specifically optimized for battery charging. Key Responsibilities: Voltage Regulation:

It wasn't a proper PDF. It was a scanned image of a microfiche, poorly converted. The title block read: .

Logic outputs indicating that the input adapter voltage is stable and within safe operating limits.
