Abstract

휴대용 무선기기의 밧데리 자동절체회로에 관한 것으로, 특히 통화대기 및 통화시간을 무한정 연장할 수 있도록 복수의 밧데리를 구성하여 로우밧데리 상태를 자동으로 감지하여 밧데리를 절체하는 밧데리 자동절체회로 및 그 제어방법에 관한 것이다.The present invention relates to a battery automatic switching circuit of a portable wireless device, and in particular, a battery automatic switching circuit for switching batteries by automatically detecting a low battery state by configuring a plurality of batteries to extend call waiting and talk time indefinitely, and a control method thereof. It is about.

휴대용 무선기기에서 통화중에 로우밧데리 경고음이 발생된 후 종지전압이 이하로 방전되면 밧데리의 전원이 차단됨으로 통화가 차단되어 밧데리 교체후 통화를 재시도 하여야 하는 문제를 해결하기 위해 액티브 밧데리의 전압을 설정전압과 비교하여 로우밧데리를 상태를 검출하여 밧데리 절체 제어신호를 출력하고, 상기 출력된 절체제어신호를 입력하여 상기 액티브 밧데리의 전원을 차단하고 스텐바이 밧데리의 전원으로 선택 절체한다.If the battery voltage is lowered after the low battery warning sound occurs during a call in the portable wireless device, the battery is cut off because the battery is cut off and the voltage of the active battery is set to solve the problem of retrying the call after replacing the battery. Compared to the voltage, the low battery detects a state and outputs a battery transfer control signal. The output transfer control signal is input to cut off the power of the active battery and selectively transfer the power to the standby battery.
