THERMAL PROTECTION
In addition to the Ovecurrent Protection, the L6228 integrates a Thermal Protection for preventing the device
destruction in case of junction over temperature. It works sensing the die temperature by means of a sensible
element integrated in the die. The device switch-off when the junction temperature reaches 165°C (typ. value)
with 15°C hysteresis (typ. value).
