LM5066I: Does the IC turn OFF the gate, if pulling timer pin over 3.9V

Part Number: LM5066I


Because this IC will start to control gate voltage if detecting power limit or current limit to limit current, I have set IC current limit much more higher we are using and build external current measurement for protections. When detecting overcurrent, i am trying to turn off gate of the IC to pulling TIMER pin over 3.9V, but in simulation it seems idea does not work? All the ideas would be beneficial...

    Hi TeHe,

    Thanks for reaching us.

    I don't think simulation model covers that. Can you please get an EVM and test ? As you are using external current measurement for detection and then turning off the GATE. Can you control UVLO/EN of LM5066i instead of TIMER pin ?

    Best Regards,
