UCC3818: To clarify the PKLIMIT function

Part Number: UCC3818

Hi Expert,

Would like to know the detail of PKLIMIT behavior.

According to the block diagram of PKLIMIT,once the threshold is triggered from this PIN.The DRVOUT should be disabled. 

The question is about once there is continuing current go through the current sense resistor and meet the PKLIMIT threshold level for a long period (50mS).

Whether the DRVOUT pin will has no any output of this pin during whole period.  

Thanks

Best regards,

Eric Lai
