Dear all
about Bq25504 VBAT_OK always 0 V,I connect BQ25504 with the datasheet figure 4.VBAT_OK =3.2V ,VBAT_UV=2.2 VBAT_OV=3.6 ,battery use LiFePO4 cell
VIN use a solar cell at 2V ,but when I remove the solar cell the VSTOR always become 0V, VBAT_OK always at 0V , so I buy an EVM use the same solar cell and change battery with Ni-Cd *2. when battery become Charging 2.2V-2.57V VBAT_OK always at 0V ,Vstor have the same problem when I remove the solar cell the VSTOR always become 0V .
