I'm hoping that someone can tell me what the Min. supply voltage allowed on the LM5068 is before the IC will start functioning. That is what supply voltage is required before the IC will follow all faults and interlocks. I know it requires 9V to release the internal interlock, is that also the minimum voltage that will keep the gate to source voltage to zero?
The function of this part is used to current limit, UV and OV protect another card on the motherboard. That board is already installed, so when the power is applied to the main card, the LM5068 will be turning on and controlling the voltage to the other card. So I expect there is a time that the LM5069 is not under control. I couldn't find that in the specification sheet.
Thanks,
John
