Our RTC battery is draining really fast. This is not a new circuit board design. In fact, we have some PCBs from the same batch with a 1546F date code and they work just fine.
We have found the same issue on few boards.
MASK : 2N02G
BATCH : PTCTCTAY1626A
Vbat drain more than 1mA, instead of 10µA ( VYBRIDFSERIESEC rev 8 says IDD_VBAT max 45µA )
Seems to be a defective batch.....
