8681l Ic Datasheet [hot] Jun 2026

The LB8681CL is designed for , widely used in:

: It dynamically allocates all remaining AC adapter current not consumed by the main system straight to the battery charging loop. This ensures the fastest safe charging parameters without overloading the external AC adapter. 2. Technical Specifications & Package Information

Below is a structured guide to help you identify which device you mean, find datasheets, and use the IC correctly. 8681l ic datasheet

| Parameter | Symbol | Rating | Unit | | :--- | :--- | :--- | :--- | | Supply Voltage | VDD | -0.3 to +6.0 | V | | Input Voltage | VIN | VSS-0.3 to VDD+0.3 | V | | Output Current | IOUT | ± 10 | mA | | Operating Temperature | Topr | -40 to +85 | °C | | Storage Temperature | Tstg | -50 to +125 | °C |

The datasheet confirms the IIP3 (Input Third-Order Intercept Point) is around -3 dBm. For a low-current LNA, this is respectable. It ensures that intermodulation products don't swamp the satellite signals. The LB8681CL is designed for , widely used

The electrical, physical, and communication parameters define how the IC interacts with a motherboard firmware: Specifications Part Markings 8681L / OZ8681LN / 8681LN Package Type QFN-16 (Quad Flat No-Leads, 16 pins) Communication Interface SMBus (System Management Bus) Programmable Battery Chemistry Support Multi-chemistry (Li-ion, Li-poly, NiMH) Architecture Role Smart Battery Charger (SBC) Current Sensing Dual high-side current sensors Pin Configuration and Architecture

It can detect a short and disconnect the path in microseconds. Technical Specifications & Package Information Below is a

Designed to work up to 85°C, it monitors its own thermal profile to prevent a meltdown. The Nokia Legacy

, the OZ8681L serves as a critical safeguard. It protects against: WIT Computers Incorrect Voltages : Preventing cell damage from power surges. Short Circuits : Mitigating fire risks through instant power cutoff. Internal Overheating

The datasheet includes a formal distinction between (general electronics) and "special application" (life‑sustaining or safety‑critical systems). It explicitly states the product is not intended or guaranteed for use in any special application that could threaten human lives in case of failure.

: High-side and low-side gate driver outputs switch external N-channel MOSFETs. This handles the high current conversion from adapter voltage down to battery charging voltage.
