TPS63805: questions

Yasushi Fujiwara

Part Number: TPS63805

Hello Experts,

I have question as follows. Would you answer them, please?
1. This device can be turned on even if the voltage (eg. 3.0V, ets.) is applied at output-pin, right? The datasheet mentioned "start up into pre-biased outputs", but I want to reconfirm. (The pre-biased voltage will not be overshoot.)
2. Regarding IFB, is a max value (100nA) specified by Tj=-40~125degC, right?
3. Over temperature protection(OVP) and Over voltage protection(OTP) will resume automatically if each status go back to normal, right?

Best Regards,
Fujiwara
