ISO35T: Total current consumption require

S Ch
Prodigy 240 points

Part Number: ISO35T

How much accually Total current consumption require to VCC1 (also supply to T1 for VCC2) , 3.6V when design follow SLUU470?

from datasheet is specfiy 60 mA, 3.6V, and Typical efficiency  60% , that mean I have to supply 3.6V and 100mA correct?

    Hi,

    Thank you for reaching out and for your interest in ISO35T.

    The maximum load on the RS-485 bus, as stated in datasheet, is 60mA. It would be best to include the max quiescent current of 16mA for for ICC2 as well. This makes the max total current ICC2 as 76mA. Hence, the input current for this 76mA is going to be 127mA considering 60% efficiency.

    The max quiescent current for ICC1 is 8mA. Considering this 8mA as well, the total current for ICC1 would be 135mA. I hope this answer your question, thanks.
