Maybe someone can help me
My old aplication uses the TC65T and an external battery connected to the BATT+ line to power up the RTC backup, and mantain the RTC when TC65T is power down.
Now I need to upgrade my aplication to the new BGS5T terminal!
How can I keep the Real Time Clock acurate when the main power supply fails to provied power to the BGS5T ?
