8.3.3 Thermal Shutdown

When the junction temperature rises up beyond TABS_R the device disables the power path and send a fault signal back to the primary side. After the thermal shutdown is triggered, the FAULT pin is asserted low. The device follows the behavior programmed by TMR (Latch-off or auto-retry). A TVS or other clamping circuit is recommended to absorb any inductive energy from the load when the device shuts down.
