Other Parts Discussed in Thread: BQ32000

Hi,

    I use BQ32000 in a Li-polyer system ,  We connect Vback Pin directly to the Battery , but I wonder the Voltage( 2.7v~4.2v ) of the battery may exceed the max voltage of the Chip.

     So we want add a resistor to the Vback Pin ,  the question : Is this design is suitable? and can you suggest me the value of the resistor ?

 

   Thanks .
