My purpose is to get 1.8V on VSTOR pin when input voltage is 0.6 V. I examined bq25570 datasheet but I didn't figure out that how can I make it. Is it related with battery that is supercapacitor voltage or CSTOR capacitor value. Because I read that If there is no storage element on VBAT, VSTOR ramped from 0V to 4.2V. How can I get just 1.8V on VSTOR pin for boost charger part. Can you explain it please?
Thanks in advance.
