thermal shutdown characteristics
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
First thermal shutdown (shuts down switch or regulator
in overcurrent)
Occurs at or above specified temperature
when overcurrent is present.

Recovery from thermal shutdown 110
°C
Second thermal shutdown (shuts down all switches and
regulator)
Occurs on rising temperature, irrespective of
overcurrent.
