Temperature Shutdown
The SCY99194 includes a temperature shutdown
protection with a trip point typically at 150°C and the typical
hysteresis of 30°C. When the temperature rises above the
high threshold, the controller stops switching
instantaneously, and goes to the off mode with extremely
low power consumption. There is kept the V_CC supply to
keep the TSD information. When the temperature falls
below the low threshold, the start−up of the device is enabled
again, and a regular start−up sequence takes place. See the
status diagrams at the Figures 41 and 42.
