FAN54063UCX Working Principle

The FAN54063UCX employs a two-stage charging algorithm consisting of a pre-charge phase and a constant-voltage charge phase. During pre-charge, the FAN54063UCX slowly charges the battery with a constant current, reducing the battery\'s internal resistance and allowing it to accept higher charge current in the subsequent constant voltage phase.

During constant voltage mode, the FAN54063UCX will charge the battery in either a constant current or constant voltage mode depending on the selected battery charging profile. During constant voltage mode, the FAN54063UCX also monitors the battery voltage and will terminate the charging cycle if it exceeds the safety threshold. The FAN54063UCX also supports temperature monitoring to ensure the battery is not over-heated.

The FAN54063UCX also includes several power saving features that enable the charger to reduce its own power consumption. This includes the ability to control the switch current and switch frequency, as well as enter low power modes when the battery is not charging.

Overall, the FAN54063UCX is a flexible, feature rich battery charger IC capable of supporting a wide range of products, including mobile phone chargers, car chargers, laptop chargers, and other products requiring battery charging and/or power regulation. Its two-stage charging algorithm, power management features, and support for window decay make it a great choice for many applications.
