8681l Ic Datasheet [ 4K 2026 ]

When deployed on a laptop motherboard, the OZ8681L functions inside a complex Power Delivery (PD) ecosystem.

designed by O2Micro. It is primarily used as a Smart Battery Charger (SBC) within portable computing systems. Technical Overview

The system does not turn on and draws zero current from the DC bench power supply.

: The device communicates via the System Management Bus (SMBus), allowing for precise software control over charging parameters such as voltage and current limits. Dual-Sensing Technology 8681l ic datasheet

Datasheets are documents that provide detailed specifications, characteristics, and applications for a particular integrated circuit. They are essential for engineers and designers when selecting and implementing ICs in electronic circuits.

In the crowded skyline of a Lenovo Yoga 2 Pro motherboard, the sits in its 16-pin QFN package, a compact square measuring just a few millimeters. To the naked eye, it’s just another black speck, but to the laptop’s 7.4V Lithium Polymer battery, it is the ultimate gatekeeper. When deployed on a laptop motherboard, the OZ8681L

This is the simplest use case—converting a higher voltage (e.g., 5V USB) to a lower, cleaner 3.3V.

: Requires specialized SMD soldering tools due to its small QFN footprint. : Often available through component distributors like

: Specifically found on laptop motherboards, including the Lenovo IdeaPad series. Related Models : Technical Overview The system does not turn on

In a different chapter of its history, variants of the 8681L were the heart of the iconic . In those luxury phones, the IC acted as a dual-band GSM signal processor, handling 900 MHz and 1800 MHz frequencies to ensure that a call placed in London would still connect in Singapore.
