Hi.
We are planning to use RTC in the DM8148- PMIC TPS6591133. Back up battery needs to be connected which is not used in DM8148 EVM. Can we connect rechargeable battery to VBACKup input? We plan to use ML-621S/ZTN (Panasonic). Please confirm whether it can be used or not? (According to datasheet recommended voltage is 2.7-5.5V). It is helpful if you can suggest a part for this ?
Regards
