Claims (1)
음성신호전송을 하는 송신회로부(10b)와, 수신을 하는 수신회로부(10a)로 구성된 무선전화기의 휴대장치에 있어서, 링신호검출회로 (5)를 통해 링신호검출을 함과 아울러 통화상태를 판별하여 링거(6)제어 및 수신회로부(10a)및 송신 회로부(10b)에 배터리전원(VB)공급제어를 하는 마이크로프로세서(300)와, 상기 마이크로프로세서(300)로부터 수신대기상태에서는 임의의 타이밍(200ms)단속적 온/오프제어를 받고, 통화상태에서는 계속 온제어를 받는 피엔피트랜지스터(TR1)를 통해 상기 배터리전원(VB)을 휴대장치의 수신회로부(10a)에 공급하도록 하는 수신부전원스위칭회로(100)와, 통화상태일때에만 상기 마이크로프로세서(300)로 부터 온 제어를 받는 피엔피트랜지스터(TR2)를 통해 상기 배터리전원(VB)을 휴대장치의 송신회로부(10b)에 공급하도록 하는 송신부전원스위칭회로(200)로 구성한 것을 특징으로 하는 무선전화기의 휴대장치 절전회로.In a portable device of a radiotelephone composed of a transmitting circuit portion 10b for transmitting a voice signal and a receiving circuit portion 10a for receiving, the ring signal detection circuit 5 detects a ring signal and determines a call state. The microprocessor 300 controls the ringer 6 and controls the supply of battery power V B to the receiving circuit unit 10a and the transmitting circuit unit 10b, and any timing in the reception standby state from the microprocessor 300. Receiving unit power switching for supplying the battery power (V B ) to the receiving circuit unit 10a of the portable device through the PNP transistor TR1 under intermittent on / off control and continuously controlled in a call state The circuit 100 and the battery power V B to be supplied to the transmitting circuit unit 10b of the portable device through the PNP transistor TR2 which is controlled from the microprocessor 300 only when in a call state. Transmitter The wireless telephone to a circle characterized in that configured in the switching circuit 200, a mobile unit power-saving circuit.※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
