MAXIMUM RATING
Stressing the device above the rating listed in the
“Absolute Maximum Ratings” table may cause
permanent damage to the device. These are
stress ratings only and operation of the device at
these or any other conditions above those indicat-
ed in the Operating sections of this specification is
not implied. Exposure to Absolute Maximum Rat-
ing conditions for extended periods may affect de-
vice
reliability.
Refer
STMicroelectronics SURE Program and other rel-
evant quality documents.
also
to
the
Table 8. Absolute Maximum Ratings
Note: 1. Soldering temperature not to exceed 260°C for 10 seconds (total thermal budget not to exceed 150°C for longer than 30 seconds).
No preheat above 150°C, or direct exposure to IR reflow (or IR preheat) allowed, to avoid damaging the Lithium battery.
CAUTION!
Negative undershoots below -0.3V are not allowed on any pin while in the Battery Back-up Mode.
