7.3.3 Thermal Shutdown Status

Internal thermal shutdown circuitry shuts down the output when the die temperature reaches approximately 160°C, resetting when the die has cooled to 140°C. The E/S pin can be monitored to determine if shutdown has occurred. During normal operation the voltage on the E/S pin is typically 3.5 V more than the negative rail. Once shutdown has occurred, this voltage drops to approximately 350 mV more than the negative rail.
