THERMAL SHUTDOWN
THERMAL SHUTDOWN
Note 1: Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is intended
to be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics.
All voltages are with respect to the potential at the GND pin, unless otherwise specified.
Note 2: Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T
= 145°C (typ).
Note 3: Human Body Model, applicable std. JESD22-A114-C.
Note 4: Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power dissipation exists,
special care must be paid to thermal dissipation issues in board design. In applications where high power dissipation and/or poor package thermal resistance is
present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (T
