Over-Temperature Protection
Over-temperature protection is based on chip temperature sensing. The minimum junction temperature at
which over-temperature cut-out occurs is 140ºC, while the typical value is 170ºC. The device is
automatically restarted when the junction temperature decreases to the restart temperature threshold that
is typically 40ºC below the shutdown value (see Figure 11) page 8..
