Thermal protection
In addition to the overcurrent detection, the L6208Q 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).
