MAX3232: Current Consumption of the Transceiver

Part Number: MAX3232

Hi Team,

I need to know about the current consumption of MAX3232EIPWR part for making power budget of my board , Its not suggested in  Datasheet , Is there any document where the current requirement is mentioned please suggest.

Regards,

Karthik

  • Karthik,
    Can you give a bit of more details about the use case, like the supply voltage, how many TX channels are on, the resistive and capacitive loading of each channel, the maximum data rate? We can provide you the power dissipation data. You can refer to this post for some discussion. e2e.ti.com/.../active-rs232-power-consumption-why-isnt-it-in-the-data-sheet

    Hi Hao,
    Thanks for your reply
    Supply voltage is 3.3V
    one TX channel is used, and am not sure about the capacitive / resistive load and max datarate is the speed that this IC supports.

    Karthik,

    In that case, you can use this graph for estimation, which shows the power data of 1 channel with 3kOhm load (most common application case).

    Please let me know if you have more questions.

    Regards,

    Hao
