5.0 Product Status Definitions
6.0 National Semiconductor B.V reserves the right to make
changes without notice to any products herein to improve
reliability, function or design. National does not assume any
liability arising out of the application or use of any product or
circuit described herein; neither does it convey any license
under its patent rights, nor the right of others.
3.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)
4.For pads with the protection circuit enabled, the protection current
must
be limited with external
source resistor Rext if the input voltage exceeds 0.4V resp 1.4V. Rext can be calculated as follows:
Rext >(Vext-1.4)/Iprotxxx).
5.Within this temperature range full operation is guaranteed.Upto +70 degrees Celsius analog perfor-
mance is not guaranteed.
