The MIC2860-2P is a high-efficiency white LED (WLED) driver designed to drive two WLEDs and greatly extend battery life for portable display backlighting and keypad backlighting in low cost mobile devices. The MIC2860-2P architecture provides the highest possible efficiency by eliminating switching losses present in traditional charge pumps or inductive boost circuits. It features a typical dropout of 52mV at 30.2mA per channel. This allows the WLEDs to be driven directly from the battery eliminating switching noise and losses present with the use of boost circuitry.
The two channels have typical matching of ±0.5%, which helps ensure uniform display illumination under all conditions. The WLEDs brightness is externally preset by a resistor and dimmed using PWM interface operating down to less than 1% duty cycle.
The MIC2860-2P is available in Thin SOT-23 and SC-70 6-pin packages with a junction temperature range of -40°C to +125°C.

1P------單極斷路器,具有熱磁脫扣功能,僅控制火線(相線),模數(shù)18mm;1P+N----單極+N斷路器,同時(shí)控制火線、零線,但只有火線具有熱磁脫扣功能;模數(shù)同樣為18mm;
本文驗(yàn)證QCC3026在2-MIC CVC下,如果調(diào)換兩個(gè)MIC的位置,即用右MIC做主,左MIC做從,是否具有可行性。 測試工具 MDE:MDE_WIN_2.3.2.126 Toolkit
1P------單極斷路器,具有熱磁脫扣功能,僅控制火線(相線),模數(shù)18mm;1P+N----單極+N斷路器,同時(shí)控制火線、零線,但只有火線具有熱磁脫扣功能;模數(shù)同樣為18mm;
在全部單相路上都一樣——僅有三種規(guī)格型號(hào)的斷路器,(剩余電流動(dòng)作斷路器)各自是1P,1P+N和2P。除此之外,在三相電路中,也有3p,3p+N和4P剩余電流動(dòng)作斷路器。三相電路中的事兒大家今日做剖析
是總開用空氣開關(guān),回路用漏電保護(hù)器。那說到這,問題來了,空開到底裝1P還是2P好呢? 對于微型斷路器來說,1P+N、1P、2P一般都用來作為單相用電器的通斷控制,但效果不同。 1P------單極斷路器,具有熱磁脫扣功能,僅控制火線(相
首先,它們最簡單的區(qū)別就是:1P斷路器它只可以單獨(dú)斷開一條線路,2P斷路器它可以同時(shí)斷開兩條線路,3P斷路器它可以同時(shí)斷開三條線路。由此可以推斷它們的應(yīng)用
微型斷路器,是建筑電氣終端配電裝置中使用最廣泛的一種終端保護(hù)設(shè)備,適用于125A以下的單相、三相的短路、過載、過壓等保護(hù),包括單極1P、二極2P、三極3P、四極4P等四種。那么單極1P、二極2P、三極3P、四極4P之間到底有什么區(qū)別呢?他們分別的作用又是什么?
