8342 ON Semiconductor Power Management Load Switch IC

The ON Semiconductor 8342 is a compact power management / load switch IC widely used on laptop motherboards to control 3.3V and 5V system power rails. This IC manages safe on/off sequencing, load switching, and over-current protection for critical motherboard sections. It ensures stable distribution of power to CPU, GPU, chipset, USB, and peripheral circuits while maintaining board safety and reducing power loss. The 8342 is commonly found in HP, Dell, Lenovo, Acer, and Asus laptops due to its reliable operation in slim SMD layouts.
