介绍了一种节能电路,对电源进行简单管理,在待机时停止对主IC供电,达到待机功耗的最小化.利用电视机遥控的编码规则,在引导码的4.5 ms低电平时间打开电源开关,给系统供电.%A kind of energy to power circuit is introduced in this paper, simple management is supplied, while stopping standby power, IC standby power consumption is stopped to minimization. Using the TV remote control, in the encoding rules guiding yards of 4.5 ms low-level time, the power switch is turned on, and the power supply is given to system.
