8682l Datasheet <2025>

Operating the IC beyond these limits can cause permanent damage to the device. These limits are for stress ratings only; functional operation at these conditions is not implied. -0.3V to +30V (Typical) GATE Pin Voltage: -0.3V to Feedback Pin Voltage ( VFBcap V sub cap F cap B end-sub ): -0.3V to +7V Current Sense Pin ( VCScap V sub cap C cap S end-sub ): -0.3V to +7V Maximum Junction Temperature ( TJcap T sub cap J ): +150°C Storage Temperature Range: -55°C to +150°C Lead Temperature (Soldering, 10 seconds): +260°C 4. Electrical Characteristics Specifications are valid at unless otherwise noted. Supply Voltage Section Under-Voltage Lockout Turn-On Threshold ( UVLOONcap U cap V cap L cap O sub cap O cap N end-sub ): 14.5V (Typical) Under-Voltage Lockout Turn-Off Threshold (

: Avoid applying excess paste to the center ground pad during installation. Excess solder under the center pad lifts the package up, causing the 16 perimeter pins to float above their respective motherboard pads, resulting in intermittent connections or no-charge faults.

: Receives raw power input from the external DC power supply brick (usually 19V to 20V in legacy laptops).

A common question in repair forums is whether the 8682L is compatible with the (likely the OZ8681L). Based on user reports, while both are battery charger ICs from O2Micro, they are not drop-in replacements and have different pin configurations and specifications. Always verify the specific requirements of your circuit before attempting a replacement. 8682l Datasheet

Open-drain output signaling whether the adapter voltage is valid and safe for use. Exposed Pad Thermal Pad

The 8682l IC is engineered for modern power electronics where high efficiency and a minimal physical footprint are required. While exact specifications can vary slightly by manufacturer, components in the 8682 series typically share core architectures aimed at optimizing power conversion and signal integrity. Core Technical Features

protocol, allowing for precise control and monitoring of the charging process. Electronics Datasheets Key Functions and Applications Operating the IC beyond these limits can cause

: If the application involves high-frequency switching nearby, add an LC filter or additional bulk capacitance to the input rail. 4. Assembly and Soldering The fine-pitch QFN package requires careful handling. Reflow Profile

: Map out communication pins (such as I2C/SMBus if applicable) and control signals to your microcontroller. AliExpress 2. PCB Layout Guidelines

When a power brick is connected, the 8682L monitors the voltage via its input logic. If the input exceeds the under-voltage lockout (UVLO) threshold, the chip asserts the ACOK signal. The internal state machine then reads commands from the SMBus lines. : Receives raw power input from the external

: The chip is marked under labels like OZ8682LN , OZ8682L , or 0Z8682L . They are cross-compatible if the package design matches the 16-pin QFN specification .

Resistors placed along the input path monitor the current drawn from the AC/DC adapter via pins ACP and ACN .

Where intelligent charging is required for safety.

: During hot-air rework, clean the center thermal pad completely. Solder the ground pad thoroughly to prevent overheating under heavy loads.
