Thermal protection
In addition to the overcurrent protection, the L6228Q integrates a thermal protection to
prevent the device destruction in case of junction overtemperature. It senses the die
temperature by means of a sensible element integrated in the die. The device switches off
when the junction temperature reaches 165 °C (typ. value) with 15 °C hysteresis (typ.
value).
