BQ34Z100-G1: What is the minimum requirement for BQ34z100-g1

Part Number:BQ34Z100-G1

Hello Ti,

I have few questions on the BQ34z100-g1.

First is about Supply Voltage. Refer to the datasheet, it recommends 2.7 - 4.5V with no operating restrictions. Does "no operation restrictions" means it works properly, like it can read the voltage, remain capacity etc. properly?

In the other hand, I would like to ask about IT enable problem. Will it possible that the BQ34Z100-g1 need another IT enable command if the chip is turned off due to disconnected power? 

Thanks for the help.
