FApplication example
FOperation notes
(1)
The IC has a built-in thermal shutdown circuit. The is a
temperature difference of 25_C (typical) between the
temperatures at which the circuit is activated and deacti-
vated.
The circuit is activated at the temperature of about 175_C
(typical), so that all outputs are turned OFF. Normal op-
eration resumes when the circuit is deactivated.
