    Hey Guys,
    I have got a problem with my PMIC eval-board. The TLF35584 supplys my C and they comunicate via SPI. I can UNLOCK the IC turn off all the watchdogs and error Monitor and lock ist again. I try wIth DEVCTRL and DEVCTRLN to get to the NORMAL Mode but the IC goes off . there is 5V at Pin V_ref but nothing at the T1&T2 and nothing at Pin LDO_Com (QUC)

    Could Somebody help me pls?

    In case you dont want to use watchdogs and error monitoring, you can connect MPS/TM pin to high always so that watchdogs and error monitoring are disabled. The device stays in INIT state providing all the output voltages.

    A step and B step

    I need to verify this still but I have a similar problem and I think it is down to the differences between different versions of the chip, make sure you have the one you think you have.
