7.3.8 Thermal Shutdown

The TPS7H3302 includes thermal shutdown circuitry that typically activates at 210ºC with a 12ºC hysterysis; when engaged the VTT and VTTREF regulators are both shutoff and discharged by the internal discharge MOSFET. This description is only provided in order to provide a complete description of the TPS7H3302; the thermal shutdown feature is not included in the product specification as the plastic package is not designed for use at 210ºC.
