SNOSDC0A October 2020 – December 2020 LM7310
The LM73100 monitors the internal die temperature (TJ) at all times and shuts down the part as soon as the temperature exceeds a safe operating level (TSD) thereby protecting the device from damage. The device will not turn back on until the junction cools down sufficiently, that is the die temperature falls below (TSD - TSDHYS).
When the device detects thermal overload, it will shut down and remain latched-off until the device is power cycled or re-enabled by toggling the EN/UVLO pin.
