BQ25504: bq25504 query

Part Number: BQ25504


Hi

My customer use this chip, OV = 3.15v, UV = 2.2v. Used the DC power supply as input VIN to simulate the solar cell.

VBAT was connected with a supercapacitor (1F, 5.5v) as the energy storage device, and VSTOR was connected with a 220ohm resistance.

When the ultracapacitor is charged to 3v, I turn off the DC power to simulate the solar panel at night, when the voltage at both ends of the VSTOR goes to zero.

Please give some suggestion.

thank you
