PRODUCTION DATA.
Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event the maximum junction temperature is exceeded. When activated (typically at 180°C), the controller is forced into a low-power reset state, which disables the output driver and the bias regulator. This feature is provided to prevent catastrophic failures from accidental device overheating.
