First Dual-mode Battery Charge ICs

News

ROHM has recently announced the availability of dual-input boost-buck charging ICs that support 1 to 4 battery cells for notebook PCs, smartphones, and power banks and is fully compatible with the the latest charging technologies such as wireless and USB Power Delivery (USBPD).

The BD99954GW/MUV generates a charging voltage from 2.56 to 19.2V for 1 to 4 cells through boost-buck control. In addition, the industry’s first dual-input charging system automatically switches charging operation without the need of an MCU by using a built-in charging adapter function. And the devive is compatible to the USBPD and USB BC 1.2 standards. This facilitates configuration of dual-mode systems capable of simultaneous charging via USBPD, or from an AC adapter.

A growing number of portable devices, including notebook PCs, are adopting the USB Type-C PD standard that can charge up to 100W, providing a common charging platform. At the same time wireless charging is gaining traction, increasing the demand to support both charging methods. However, in order to deliver a wide power supply range required by USBPD, a boost function must be added to the system to charge 2-cell (~8.4V) batteries from conventional 5V chargers.

In response, combining proprietary semiconductor technologies allowed ROHM to meet these needs and develop dual-input charging ICs that support both USBPD and 5V inputs in a single package.
