Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond
the Recommended Operating Ranges limits may affect device reliability.
5. Operation above 5.5 V input voltage for extended period may affect device reliability.
6. Including de−ratings (refer to application information section of this document for further details)
ELECTRICAL CHARACTERISTICS
Min and Max Limits apply for T_J up to +125°C unless otherwise specified. PV_IN = 3.6 V (Unless otherwise noted). Typical values are
