器件的双uvlo功能保护功率MOSFET不会因栅极驱动或电源电压过低而损坏。

Its dual UVLO feature protects the power MOSFET from damage in the event that the gate-drive or supply voltage is too low.

如果一台发电机组没有运转，并且没有逆功率继电器保护，运转的机组就会驱动这个机组，这台机组上的发电机则变成电动机运行。

If one set stops and reverse power protection is not provided, the set still running will drive the set that has stopped. The generator on the set that has stopped will act as a motor.
