PMIC – Battery Management plays a very important role in the industrial, automotive, communication and several other industries. It helps in proper charging and maintenance of rechargeable batteries, enabling prolonger and safer use of these batteries. This article would cover the application field and working principle of each and every factor related to FSA9485UCX.FSA9485UCX is a dual-channel control, four-port based USB switch solution from Fairchild Semiconductor. It is designed for portable electronic devices, smart phones and tablets, where USB ports are usually powered externally. Compatible with any USB based application, FSA9485UCX offers an integrated fault detection mechanism and over-current detection as well as protection from discharge.Since FSA9485UCX performs a single device integration, it works on a low power control solution, with a low voltage dropout requirement (LDO). It is a type of integrated circuit used to control the flow and manage the charging of the battery in various devices. The FSA9485UCX operates on the principle of switching the current source, which permits the selection of the most preferred source of energy according to the need.With ultrafast minimum switch propagation delay, the FSA9485UCX offers maximum availability and reliable switching operation environment. The device can also work as an access peripheral IC, by connecting the VCC pin to the power source. Once the access peripheral is connected, it can be used as a peripheral device to switch change the power source or its direction.The FSA9485UCX features USB Type C supporting power using one-line configuration. It can be used for detecting the status of the device, handling the power signal between the power sources such as the battery or the power supply and then switching the power source between the sources. The device can also act as a Fault Handler in order to detect and protect the device from over-current or discharge situations.Moreover, the integrated safety feature helps in minimizing the risk of leakage and eliminates chances of fire or any other kind of hazard caused due to improper handling of the device. The low voltage dropout requirement also ensures that the device maintains high reliability during power delivery.The device is also compatible with Universal Serial Bus (USB) 3.1 standard. This makes it very suitable for use in latest mobile devices like laptops, tablets and smart phones. In addition to this, it is also suitable for Quick Charge 3.0 and QC 4.0 applications.FSA9485UCX is an ideal solution for charging troubles, as it can enable high current switching which enables easy and efficient device charging. It supports up to two maximum current paths in order to enhance the current flow rate.Overall, the FSA9485UCX from Fairchild Semiconductor is a low power consumption, robust control solution for portable electronic devices that provides multiple features for protecting, monitoring and preventing any kind of fault in the device. Its ultra-fast minimum switch propagation delay, power fail-safe operation, integrated safety features and compatibility with USB 3.1 standard make it an ideal solution for all kinds of applications.
