Ideal for Laptop and Portable Device Repair

This BQ24740 integrated circuit is a common component found on the motherboards of many laptops and other portable electronics. It often serves as the primary controller for the battery charging circuit. If your device is failing to charge its battery, displaying incorrect battery levels, or not recognizing the AC adapter, a faulty charging IC like this could be the culprit. Technicians with the right skills can use this component to perform board-level repairs, offering a cost-effective alternative to replacing an entire motherboard. This part is available to help you complete your repairs successfully.

Package and Physical Specifications

The BQ24740 comes in a 28 LD QFN (Quad Flat No-lead) package. This is a surface-mount package with a small footprint, making it ideal for space-constrained designs in modern electronics. The compact size requires precision and specialized equipment for installation. Our listing is for two brand new pieces, supplied in a reel package to ensure they are protected during transit and storage. The provided images are of the actual item, so you can see exactly what you will get when you purchase this part.

Professional Installation Required

Please note that replacing this component is a task for experienced technicians. A successful replacement requires specialized tools, including a hot-air soldering station for removal and installation, and a pre-heating station to prevent thermal shock to the PCB. You should only order this item if you have the necessary skills and equipment for surface-mount device (SMD) rework. Proper technique is essential to avoid damaging the component or the motherboard during the repair process. This is not a task for beginners in electronics.

Important Handling and Preparation

This integrated circuit is a moisture-sensitive device and also highly susceptible to Electrostatic Discharge (ESD). It is crucial to handle the chip using proper ESD-safe practices, such as wearing an anti-static wrist strap and working on an ESD-protected surface. Before soldering, it is mandatory to prebake this chip at 125 degrees Celsius for a full 24 hours. This process removes any absorbed moisture, which prevents the chip from being damaged by the rapid heating (popcorning effect) during the reflow soldering process, ensuring a successful installation.
