MAXIMUM RATING
Stressing the device above the rating listed in the
âAbsolute Maximum Ratingsâ 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 also to the
STMicroelectronics SURE Program and other rel-
evant quality documents.

Note: 1. For SO package, standard (SnPb) lead finish: Reflow at peak temperature of 225°C (total thermal budget not to exceed 180°C for
between 90 to 150 seconds).
2. For SO package, Lead-free (Pb-free) lead finish: Reflow at peak temperature of 260°C (total thermal budget not to exceed 245°C
for greater than 30 seconds).
CAUTION: Negative undershoots below â0.3V are not allowed on any pin while in the Battery Back-up mode.
CAUTION: Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.
