5.The protection current can be calculated as follows:
In case P1[6]/PON, P1[7]/CHARGE, VBAT3, P2[3]/ADC1 is input, Iprotxxx_max = (Vext -
2.55)/(500+Rext)
Rext is an external resistor which is needed if the external voltage Vext exceeds the 2.8V.
(A lower protection current value of e.g. 100 uA is recommended in case power saving is important)
In case P1[6]/PON, P1[7]/CHARGE , P2[3]/ADC1 is output, Iprotxxx_max = (VDDIO - 2.55)/(500)
Table 2. OPERATING CONDITIONS

1.Within the specified limits, a life time of 10 years is guaranteed.
2.Full operating mode; the differences between AVD, VDD may never be more than 300mV; during a
short period of time e.g. during power up more than 300mV difference is allowed. Analog performance
is only guaranteed from 1.75-1.98V
