Note:
Thermal limiting circuitry on chip will shut down the cir-
cuit at a junction temperature of about 160
°
C. The device
should never be exposed to this temperature. Operation
above 145
°
C junction temperature may degrade device reli-
ability. See the SLIC Packaging Considerations for more in-
formation.
