We will introduce the BD99954 series of buck-boost charge ICs by promoting their compatibility with the latest charging methods adopted by notebook PCs, tablets, and portable batteries.
The BD99954 series supports 1- to 4-cell battery applications, and are offered in ultra-compact CSP and QFN package types.
<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.
Thank you!
