电视遥控器均采用CMOS集成电路,耗电极微。不按键时电流仅几微安,有些甚至还不足1μA;按键时电流为数毫安至十几毫安(随型号而异)不等。所以电池使用寿命很长,正常时可达一年以上。所谓“耗电快”,是指新电池使用不足三个月即失效。这通常有以下几方面原因。 TV remote control are CMOS integrated circuits, micro power consumption. When not pressing the current only a few micro-amps, some even less than 1μA; button when the current is a few milliamps to a dozen milliamperes (varies by model) ranging. So the battery life is very long, up to more than one year when normal. The so-called “fast power consumption,” refers to the use of new batteries less than three months that is invalid. This is usually the following reasons.
