ULN2803A: Is there "Duty Cycle(%) - Output Current(mA)" graph?

Guru 21745 points

Part Number: ULN2803A

Hi Team,

My customer considers to replace a competitor device to ULN2803A.
I was asked if there is "Duty Cycle(%) - Output Current(mA) under 8 channel is all on" graph.

Do you have the data?

Best Regards,

  • Hi Yaita,

    As of right now, we do not have this curve. Do you have the amount of current the customer would like to put through each channel?

    Thanks,

    Hi Alek-san,

    Thank you for your kind reply.

    >Do you have the amount of current the customer would like to put through each channel?
    I heard he wants to put through 400mA per channel.

    Your support would be appreciated.

    Best Regards,
    Yaita

    Hi Yaita,

    The total maximum current for the device is 2.5A. If all eight outputs are powering 400mA loads, then this would be a total current of 3.2A, and the device cannot support this.

    Thanks,

    Alek Kaknevicius
