TLV9054: DC input under no power condition

TLV9054: Similar question for limit current at input of TLV521

Part Number: TLV9054
Other Parts Discussed in Thread: TLV521

Tool/software:

What would be the limit of the input current for the TLV521 when it is not powered? This is not mentioned in the data sheet. Would 10mA be a safe number?

    Ashvin,

    10mA probably would not be damaging. 1mA is more reasonable. Keep in mind that this positive current will primarily go to V+ supply pin. Is this input voltage, current enough to actually power up the V+ bus and everything on it?
