Note : Permanent device damage may occur if Absolute Maximum Ratings are exceeded.
Functional operation should be restricted to the Recommended DC Operating Conditions detailed in this data sheet.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.
(1) Soldering temperature not to exceed 260° C for 10 seconds (Total thermal budget not to exceed 150° C for longer
than 30 seconds).
Caution : Negative undershoots below – 0.3V are not allowed on any pin while in the Battery Back-up mode.
