The is most likely a low-dropout linear regulator optimized for battery-powered applications. While its official datasheet can be challenging to locate due to its regional manufacturing base, the electrical characteristics, pinout, and application notes provided in this guide offer a strong starting point for engineers and hobbyists.
For specific design requirements, it is highly recommended to obtain the detailed functional block diagram and electrical specifications directly from O2Micro or a certified distributor to review the full 8682L IC datasheet.
The output from Pin 1 is often routed internally to generate other signals. For instance, ACAV (AC Adapter Voltage) output has been measured at . This signal is used to enable or indicate the presence of a valid input voltage from the AC adapter. Without a full datasheet, these pins and voltages provide a practical starting point for troubleshooting. 8682l ic datasheet
: Supports Li-Ion batteries with 1 to 4 cells and various other chemistries.
The 8682L functions as a synchronous buck battery charger controller designed specifically for multi-cell Lithium-Ion (Li-Ion) or Lithium-Polymer (Li-Po) battery packs found inside portable laptops, netbooks, and tablets. Mechanical and Physical Characteristics Quad Flat No-leads 16-Pin ( QFN-16 ). The is most likely a low-dropout linear regulator
Often, the charger IC fails along with the DC-DC MOSFETs connected to it.
| IC | Dropout | Iq (typ) | Max Iout | Enable | Best For | |----|---------|----------|----------|--------|----------| | | 0.6V | 3mA | 300mA | No | Cost-sensitive, moderate current | | 78L05 | 1.7V | 3mA | 100mA | No | Legacy designs, lower current | | LM1117 | 1.2V | 5mA | 800mA | No | Higher output current | | MCP1700 | 0.18V | 1.6µA | 250mA | No | Battery-powered (low Iq) | | AP2112 | 0.3V | 55µA | 600mA | Yes | Enable + low dropout | The output from Pin 1 is often routed
Operating as a Level 2 smart charger, the device responds to commands from either the host system or a smart battery pack directly. It dynamically steps down high adapter voltages to target battery profiles.
