Want to remove 0.1ohm series resistors from PMU.

Hi Community,

 

We'd like to ask something about 0.1ohm series resistors of PMU.

 

There are 0.1ohm series resistors connected to 22uF and 10uF of BATTERY and VDD4P2 pin respectively.

The schematics of the EVK Rev. A mentions that the resistors are "to prevent possible battery charger oscillation."

We are making a custom board which will not connect battery and would like to remove these 0.1ohm resistors.

Did anyone develop a custom board with no-battery configuration and also without these 0.1ohm resistors?

If someone did that, was there any problem?

From the description of the schematics, I suppose there will not be any problem but we would like to make sure of that before making a board.

 

Thank you in advance,

Hikaru
