The Industry's First Dual-Mode Batterry Charger IC |
|
|
|
The BD99954GW/MUV generates a charging voltage from 3.07 to 19.2V for 1 to 4 cells through boost-buck control for USBPD. In addition, the industry's first dual-input charging system automatically switches charging operation without an MCU using an original built-in charging adapter function. Support is provided for both USBPD and USB BC 1.2, facilitating configuration of dual-mode systems capable of simultaneous charging via USBPD, wirelessly, or from an AC adapter. |

ROHM Chip Resistors for Current Detection PSR/GMR/PMR/PML Series |
|
|
|
ROHM shunt resistors were developed using metallic material processing technology cultivated over many years to ensure compatibility with a wide range of applications, from portable devices such as smartphones to automotive and industrial systems requiring a greater degree of reliability. This allowed ROHM to adopt a special high performance alloy for the resistive element that provides high accuracy current detection with excellent temperature characteristics. |
