. It is primarily used as a Smart Battery Charger (SBC) within laptop power management systems. Jotrin Electronics Core Specifications Manufacturer O2Micro International Ltd. Package Type (16-pin Quad Flat No-lead). Operating Temperature : Extended range from -40°C to 105°C Communication Interface
If the power brick starts pushing too much, the 8681L shuts the gates.
| Feature | 8681L (Low Power) | BGA7L1N6 (Infineon) | MAX2659 (Maxim) | | :--- | :--- | :--- | :--- | | | 10 mA | 4.7 mA | 4.1 mA | | Noise Figure | 0.8 dB | 0.7 dB | 0.8 dB | | Gain | 27 dB | 18.5 dB | 20.5 dB | | Voltage | 2.7-5.5V | 1.5-3.6V | 1.6-3.6V | 8681l ic datasheet
The 8681L is typically housed in a compact, thermally enhanced SOP-8 (EP) or DFN package. Below is the standard pin layout and description. Pin Number Description BS
The (often marked as 8681L or OZ8681LN ) is a highly integrated, SMBus programmable, multi-chemistry battery charge controller . Designed predominantly for single-battery portable computer systems, this integrated circuit (IC) serves as a critical Smart Battery Charger (SBC) . It is a foundational component in laptop power management, frequently found on motherboards for modern computing electronics like Lenovo IdeaPad systems. Package Type (16-pin Quad Flat No-lead)
The 8681L uses dual high-side current sensors to actively monitor total power draw. When the laptop is powered on and running heavy tasks, the IC dynamically allocates all leftover current from the AC adapter to the battery charger. This guarantees that the system runs at maximum performance while minimizing battery charging time. 2. SMBus Programmability

It is often confused with its sibling, the 8681 (without the 'L'), which operates at higher current. The typically denotes a low-power or low-current version , making it ideal for battery-operated handheld GNSS receivers.
Monitors the physical presence of the AC charging adapter and the overall pack voltage. Below is the standard pin layout and description
| 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 OZ8681LN is a specific power management IC. The Win Source catalog notes that "the supply and demand status is limited". It is "a good choice for those who are looking for an electronic component that is suitable for their needs and requirements".
