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

Lars Hummel

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.
