Is it safe to connect supercap (120 F charged to 4 V) instead of li-ion battery to ADP5062? ADP5062 won't be used to charge the supercap, it will be used just for powerpath controlling. The supercap will be charged by external supercap charger.
ADP5062 is designed for Li-ion battery charging with power path management. Please kindly refer to the datasheet to ensure the electrical characteristic of our part meet your application requirement. Something coming across my mind for your reference:
1. Peak current flowing between ISO_S and ISO_B causing heat on IC which should not exceed our spec; our isolation FET comes with 54mohm(typ) and 89mohm(max).
2. Max voltage rating of supercap connected to our IC also need to be under our operating rating to ensure proper functionality.
3. Ensure ADP5062 is disabled charging function when you have another supercap charger enabled.
The above are just something coming across my mind but not limited to all the things you should consider. I hope this helps. Thank you
