(2) High voltage devices such as the TPS92311 are susceptible to increased leakage currents when exposed to high humidity and high
pressure operating environments. Users of this device are cautioned to satisfy themselves as to the suitability of this product in the
intended end application and take any necessary precautions (e.g. system level HAST/HALT testing, conformal coating, potting, etc.) to
ensure proper device operation.
(3) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T
