ADM1272 Enable pull low to gate start sinking current response time

Hi ADI Expert

May I know if there is a spec for the delay time when the enable pin is detected low to gate start sinking current to shut the external Mosfet off?

thank you 

Ken

    Hi Ken,

        There is no spec for that, however, it is significantly less than 1us. This is more than an order of magnitude faster than the time that it takes to pull the GATE node down to the SOURCE node and turn off the FET, which is usually something like >20us.

    Thanks!
