: Optimized for high-fidelity audio performance in some compact form factors, offering a lower noise floor compared to alternatives like the RT6338B. Implementation & Troubleshooting Tips
(commonly referred to as the ) is a highly integrated, SMBus-programmable, multi-chemistry battery charge controller manufactured by O2Micro. It is designed to act as a Smart Battery Charger (SBC) within portable computer systems (such as laptops). Jotrin Electronics
The OZ8681L is widely available from electronic component distributors. It is typically sold in a standard QFN-16 package, making it suitable for automated assembly. Pricing varies significantly based on the quantity purchased. From market research, approximate per-unit pricing follows this scale: 8681l ic datasheet
| Pin Number | Pin Name | Function | | :--- | :--- | :--- | | 1 | | Output Pin (Connects to MCU or Load Driver) | | 2 | VSS / GND | Ground | | 3 | IN / KEY | Sensor Input (Connect to Touch Pad) | | 4 | AHLB | Output Logic Select (VDD = Active High, GND = Active Low) | | 5 | VDD | Power Supply Input | | 6 | CS / SENS | Sensitivity Adjustment Capacitor Pin |
Depending on the specific motherboard revision, the IC is commonly packaged in a compact housing. Key functional pins include: : Optimized for high-fidelity audio performance in some
The most common reason a technician will encounter the OZ8681L is a laptop that refuses to charge the battery. Many forum discussions revolve around this exact issue. According to repair notes, the problem is often not the IC itself but the conditions required for it to operate.
To ensure safe operation in demanding laptop motherboards, the 8681L integrates several hardware-level safety features: Over-voltage protection (OVP) to prevent cell degradation. Jotrin Electronics The OZ8681L is widely available from
Defines the valid supply voltage (2.2V to 7.5V) and input voltage thresholds (VIH, VIL) for proper logic level interpretation.
The (often marked as 8681L ) is a highly integrated, SMBus-programmable battery charge controller manufactured by O2Micro . It is primarily used as a Smart Battery Charger (SBC) in notebook and netbook computer systems to manage the complex charging requirements of multi-chemistry batteries.
