TPSI3050-Q1: Max current out of PXFR if R_PXFR = 0 Ohm

Part Number: TPSI3050-Q1

We want to set the TPSI3050-Q1 in lowest power mode by placing a 0 Ohm resistor on the PXFR pin. 

For our derating analysis we need to know the max. current that the PXFR pin will "deliver".  

  • Hello Lars,

    Thanks for reaching out on E2E. At the lowest power transfer setting, the device will transfer 0.77-mA to VDDH. Can view this table in the "power transfer" tab in our calculator tool. Let me know if I am misunderstanding your question. 

    Best regards,

  • Hi Tilden, 

    thanks for your answer - we are doing a derating on our components, therefore we have to know the voltage or current our components will see. 
    As I put a 0 Ohm resistor on the PXFR-pin - we need to know what current this 0 Ohm resistor will see. 
    In other words, what is max. current that the PXFR-pin will "deliver".

    Thanks in advance.

  • 75uA maximum and  is only presented during power up. Once power up is completed and the RPXFR setting is configured, this current is removed.
