BD82001FVJ-E2 are ideal for applications requiring multiple power domains such as smartphones, tablets, portable media players, hard drives, and other types of consumer electronic devices. The integrated circuit is well suited for controlling both static and dynamic power transfer. It has the ability to quickly switch between each power domain, while also providing current control and protection of the devices connected to each domain. The integrated circuit dynamically detects current demand and adjusts power delivery as needed.

BD82001FVJ-E2 is a high-performance, low-power, low-dropout power management integrated circuit and works at a nominal voltage of 1.3 to 4.8V. BD82001FVJ-E2 supports multiple power domains and can switch at the same time 2 or 3 power domains with two or three or four channels. The integrated circuit integrates four power MOSFETs and OVP/UVP/OVT/Tj-L protection functions.

The IC integrates four N-Channel MOSFETs for power transfer, with a low on-resistance of 0.20 Ω in order to obtain a high-efficiency power transfer. Furthermore, the integrated circuit can adjust an external resistor to measure the current flow. It has a maximum tolerance of 1% and a typical value of 1.5%. This can be used to detect short circuits, over temperature and excessive current.

Overall, the BD82001FVJ-E2 can be used in a variety of applications, primarily in the field of power management for portable convenience devices. It provides an integrated solution for switching and controlling power, as well as fault detection and protection. Furthermore, its low on-resistance and 1.3-4.8V voltage range make it ideal for efficient, low-power applications.
