Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be

impaired.

Note 2: The device is guaranteed to meet performance specifications from 0°C to 70°C.

Specifications over the -40°C to 125°C operating junction temperature range are

guaranteed by design, characterization and correlation with statistical process controls.

Note 3: This IC includes over temperature protection circuit inside that is intended to protect the

device during momentary overload conditions. Over temperature protection trip point is

around 160°C. Continuous operation above the specified maximum operating junction

temperature may impair device reliability.
