Acting as a switching regulator in laptop power supplies or chargers.
Negative differential input pin for the battery charging current sense resistor. Analog Input : A standout feature that allows the battery
: The OZ8681L, also from O2 Micro, is a related device. However, it is crucial to note that it serves a different purpose. The OZ8681L is a smart battery charger (SBC) with SMBus programmability for battery management, whereas the 8682L is part of the main power supply generation circuitry. Technicians have questioned the compatibility between the 8681L and 8682L, and they are generally not interchangeable due to these different roles.
Drivers CHG_OUT (Pin 9) and BGATE (Pin 12) actuate transistors Q1 and Q2 alternately to step down adapter voltage to safe charging parameters. Loop Filtering: Decoupling capacitors (typically Analog Input : The OZ8681L, also from O2
The (also referred to as 8682L or OZ8682LN ) is a highly integrated SMBus Level 2 Battery Charge Controller manufactured by O2Micro . It is primarily designed for use as a Smart Battery Charger (SBC) in portable computer systems, such as laptops. Key Technical Specifications
