8682l Datasheet ^hot^

The chip comes in a small QFN-16 package (3x3mm or 4x4mm). It is highly sensitive to Electrostatic Discharge (ESD); safety protocols like anti-static wrist straps are mandatory.

A: Almost certainly a regulator. If you measure continuity between pins with a multimeter, a transistor would show diode junctions between all three pins. A regulator will show high resistance (>1k ohm) between IN and OUT.

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.

While engineers must consult the exact manufacturer layout diagram for full thermal thresholds, the 8682L datasheet establishes strict operation envelopes: Standard Value Range / Specification QFN-16 (Quad Flat No-Leads, 16 pins) Interface Protocol SMBus Compliant (Level 2 Charging) Input Voltage Range Typically supports 4.5V to 24V adapter inputs Charging Voltage Accuracy (critical for Li-ion safety) Switching Frequency Fixed internal oscillator (typically ~300kHz to 500kHz) Pinout Configuration (QFN-16 Architecture) 8682l Datasheet

: Utilizes the System Management Bus (SMBus) protocol to communicate with the host controller and the smart battery, providing real-time data on charging status. Technical Specifications

The OZ8682L is a common point of failure in motherboard repairs, often cited in forums for various Lenovo models:

Commonly used in the 820-2936-B logic board for managing power and charging cycles. Datasheet Resources The chip comes in a small QFN-16 package (3x3mm or 4x4mm)

This is usually caused by poor loop stability. Adjust the resistor and capacitor values on the COMP pin to tune the error amplifier loop response. If you measure continuity between pins with a

The OZ8682L is an EOL (End of Life) component and is no longer in mass production, but it is still available from various online component distributors and marketplaces. Some sources include:
