Installing this IC requires skills due to its small QFN-16 footprint. 1. Diagnostic Symptoms Laptop only works on AC power. Battery "plugged in, not charging." Internal overheating near the charging circuit. Short circuits on the motherboard charging rail. 2. Tools Required Hot air rework station (set to approx. 350°C–380°C). Fine-tip soldering iron. High-quality flux and solder wick. Microscope (highly recommended for QFN alignment). 3. Installation Steps Preparation: Apply flux to the existing IC pins.
: It serves as a programmable PWM battery charger that dynamically allocates AC adapter current between the system and the battery to ensure the fastest charging possible. Package Type : Typically available in a (Quad Flat No-lead) surface-mount package. Temperature Range : Designed to operate reliably between -40°C and +85°C Communication : Utilizes the protocol for programmable charging parameters.
