NOTE 1: Therm output stage is on in the normal temperature range
NOTE 2: In the Tal-Tll temperature range therm signal follows the inverted Fstart signal. After Tll temperature this output is always in high
impedance. If thermal shutdown is reached this pin will remain in this state un til the shutdown hysteresys will be recovered.
