base-emitter voltage

基本解釋

Consequently, no load current flows through R6 because Q2, whose base-emitter voltage is now 0V, has turned off.
由于Q2的基極-發(fā)射極的電壓為0V而截止，因此沒有負(fù)載電流流過R6。

When choosing a value for R6, ensure that Q2's base-emitter voltage is less than approximately 0.5V at the maximum permissible value of the load current.
選擇R6的阻值時要確保在負(fù)載電流的最高允許值的條件下，Q2的基極-發(fā)射極電壓大約低于0.5V。

In the event of an overload when ILOAD exceeds its maximum permissible value, the increase in voltage across R6 results in sufficient base-emitter voltage to turn on Q2.
當(dāng)ILOAD超過最大允許值時發(fā)生過載情況，R6上的電壓增大導(dǎo)致基極-發(fā)射極電壓足夠大到導(dǎo)通Q2。
