Other Parts Discussed in Thread: BQ25570
I have a question about the Rin on the bq25570 evmboard.
I think the value of Rin, the resistance to the VIN_DC terminal on the board, is 2.27k ohms.
I want to know exactly how much this is.

Hi Sanghyun,
Are you referring to the resistance from VIN_DC pin to GND when VSTOR=0V? We haven't characterized that value.
Keep in mind, there is an NFET from VIN_DC to ground that turns on if VIN_DC=VMPP > VBAT_OV to prevent over-voltage on the storage element.
