Part Number: BQ25504

Hi,

Below is BQ25504 efficiency graph from document page 7.

I would like to ask followings:

Q1. For those graphs, what is the load resistance?

Q2. For figure 1, how do you set voltage of VSTOR to be 1.8 or 3 or 5.5V? By setting OV resistor values?

Thank you.

Hello,
1. The load was set by the keithley source meter.
2. The voltage of VSTOR can be set by VBAT_OV resistor value, and also in this case it was set by keithley source meter.
