Maximum ratings

Maximum ratings

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 indicated in the operating sections of

this specification is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability. Refer also to the STMicroelectronics SURE

Program and other relevant quality documents.

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).

Negative undershoots below –0.3 V are not allowed on any pin while in the battery backup

mode.
