Hello,

My customer has questions.
About the following three devices, how much time does it take from VUVLOF triggered to Vout is shut down respectively?

    Hello Hirano-san, 

    We are double checking with our backend team to get you the right information. 

    Thanks,

    After reaching out to the design team they said the VBB_UV response time is not a spec that is normally measured.

    When VBB_UV condition happens, gate pull-up is going to be disabled, and gate will be pulled down by passive VGS resistor. Therefore, pull-down will be relatively slower than active pull-down

     it could take about 50~100us depending on supply voltage. Since this is not specified in the datasheet, use this value only as reference when testing. 

    Best, 

    Alan
