LM5169FQEVM: Input Current for EN/UVLO pin

Gerald

Part Number: LM5169FQEVM

Hi Team, 

May I ask for help? Our customer wants to know data for Input nominal and Maximum Current for EN/UVLO pin.

I hope you can help us with our customer concern. Thank you so much in advance.

Kind regards,
Gerald

    Hello

    We do not specify the input currents to the EN/UVLO pin for this device.

    The current into this pin will consist of small leakage currents that should be in the hundreds of nA.

    If you need more information, please contact me through TI email.

    Thanks

    Hi Frank,

    Thank you for your previous response. Please be informed that I still got a reply from our customer as shown:
    "Because this component is designed to operate a very high voltage starter circuit.
    It was chosen because of its low current consumption at this time
    More accurate data is needed on this current consumption at the input in order to examine the maximum size of the resistor for sampling the input voltage to the component for operation.
    And I would like to activate it with an input resistor of 10M ohm, and consequently its effect in all temperature conditions."

    I hope you can further help us. Thank you.

    Hello

    TI does not reccomend external resistor values larger than 1M for this device.

    The typical value of leakage current on this pin may be as high as 100nA.

    Thanks

    Hi Frank,

    I am sorry. Our customer is still asking below: 

    "Pleas send my more detail for maximum leakage This pin:
    at min and maximum temperature
    and direction (sink or source) when the input Voltage is near 1.5 volt."

    I hope you can still help us further. Thank you so much.

    Kind regards,
    Gerald

    Hello

    Unfortunately, we do not have data on the EN input current.

    Thanks
