user wants a long article about the "8681l ic datasheet". I need to search for information about this component, likely a relay driver IC. I will follow the search plan. search results show multiple possible ICs with "8681L" in the name. To get a comprehensive understanding, I need to open several of these relevant results simultaneously. search results indicate that "8681L" likely refers to either the OZ8681L battery charger IC or the LB8681CL motor driver. The OZ8681L from O2Micro appears to be the most relevant component for laptop battery charging, with detailed specifications available. The LB8681CL is a motor driver. I'll now proceed to write a comprehensive article based on the gathered information. search results provide information on two possible "8681L" ICs: the OZ8681L battery charger and the LB8681CL motor driver. The OZ8681L appears to be the primary focus for the article. I will now structure a comprehensive article covering its overview, key features, applications, pinout, and troubleshooting. is a detailed technical article that consolidates the available information on the '8681L' IC.
This article is for informational purposes. Always refer to the original component manufacturer's datasheet for current specifications.
The LB8681CL is a purpose-built motor driver. It is described as a "low-voltage, low-saturation 1.5-channel constant current forward/reverse driver IC". It is designed for direct drive from a microcontroller, making it ideal for controlling voice coil motors (VCMs) in applications like shutter and aperture control in cell phone cameras. The "1.5 Channels" and "H-bridge" structure allow for complex motor control, including the ability to reverse direction.
: A total short-circuit inside the OZ8681L can pull down the primary power rail (e.g., VIN or 19V rail), preventing the laptop from triggering any power-on state.
