Thermal Shutdown
The NCP1090/91/92 include a thermal shutdown which
protect the device in case of high junction temperature. Once
the thermal shutdown (TSD) threshold is exceeded, the
classification block, the pass switch and the PGOOD
indicator are disabled. The NCP109X returns automatically
to normal operation once the die temperature has fallen
below the TSD low limit.
