維安新品推薦|Smart Low Side Power Switch智能低電壓端電源開關(guān)WP6420
The WP6420 circuit use N channel lateral MoSas POWER FET embedded protection functionswhich consist of thermal-shutdown circuit,currentlimitation circuit,Overload protection circuit andshort circuit protection. When the circuit is shortcircuited,current limitation circuit is firstly triggeredand a high current flow through POWER FET whichled to high temperature of POWER FET.And thenthe thermal-shutdown circuit is triggered to shutdown the circuit. So the current limitation circuit andthermal-shutdown circuit act as the short circuitprotection role.
WP6420電路采用N通道橫向MOSAS功率場效應(yīng)管嵌入式保護(hù)功能,包括熱關(guān)機(jī)電路、電流限制電路、過載保護(hù)電路和短路保護(hù)電路。當(dāng)電路短路時(shí),首先觸發(fā)限流電路,大電流流過功率場效應(yīng)管,導(dǎo)致功率場效應(yīng)管高溫,然后觸發(fā)熱關(guān)斷電路關(guān)閉電路。因此,限流電路和熱停電路起著短路保護(hù)的作用.
The WP6420 circuit features low on resistance,considerable load current. The input voltage canvary from 0V to 10V.The device is available in sOT-223 package.
WP 6420電路具有低的電阻,相當(dāng)大的負(fù)載電流。輸入電壓可以在0V到10V之間變化,器件可以在St-223封裝中使用。
