<Key Features>
1. Dual-input charging system
Conventionally, configuring dual-input charging systems requires external components along with a control MCU to switch the charge input path.
In contrast, the BD99954 series incorporates all necessary functions on a single chip, significantly reducing design load along with mounting area.

2. Supports the latest USBPD standards
Buck-boost control makes it possible to charge batteries from a variety of output voltages, including USBPD that supports 5V, 9V, 15V, and 20V power profiles as well as wireless chargers providing 5V and 9V output.
