5.6.2
Overvoltage protection (OVP)
In case the VOUT(FB) pin is detected above the VOVP threshold, the output overvoltage protection is triggered.
When this occurs, the RST pin is forced low and the L7983 actively discharges the output voltage by sinking
current (refer to Section 5.6.1 Overcurrent protection (OCP)).

As soon as the OVP cause is removed, the proper switching activity is restored and RST output is released, with
the delay and threshold described in Section 5.4 .
5.6.3
Overtemperature protection (OTP)
If the device junction temperature increases above TSHDWN (165 °C typ.) the switching activity is inhibited until a
temperature drop of THYS (30 °C typ.) is detected.
When the switching activity is resumed, a soft-start is implemented. The OTP protection is always active.
