Abstract
본 발명은 무선 전화기의 배터리 충전회로 및 방법에 관련된 것으로서, 종래에는 고정장치에 휴대장치를 세워 접속하거나 높혀 접속하여 충전하는 경우 고정장치측 충전단자의 극성과 휴대장치측 충전단자의 극성이 일치하지 않게 접속될때도 있어 휴대장치측의 배터리에 충전이 이뤄지지 않게 되는 문제점이 있었다.The present invention relates to a battery charging circuit and a method of a cordless telephone. In the related art, when a portable device is connected to a fixed device in an upright position or connected to a mobile device, the polarity of the fixed device side charging terminal and the mobile device side charging terminal do not match. There is a problem that the charging is not made to the battery of the portable device side even when not connected.
본 발명은 이러한 종래기술의 문제점을 개선할 수 있도록 이들 고정장치와 휴대장치측의 충전단자가 그 극성 이 일치하지 않게 접촉되더라도 휴대장치측 배 터리를 충전할수 있는 무선전화기의 배터리 충전회로 및 방법을 제공한다.The present invention provides a battery charging circuit and method for a wireless telephone that can charge the battery of the portable device even if the terminals of the fixing device and the charging terminal on the portable device are not in contact with each other so as to improve the problems of the related art. to provide.
