LV49152V
Thermal protection circuit
The LV49152V includes a thermal protection circuit to prevent damage to or destruction of the IC should abnormal
internal heat generation occur.
This means that should the IC junction temperature (Tj) rise above about 175
°C due to inadequate heat dissipation or
other reason, the thermal protection circuit will operate to stop IC operation should the temperature rise further.
If the temperature is reduced by lowering the input level or other means, the thermal protection circuit will recover
automatically (about 105
°C).

* The thermal protection circuit is a function to avoid the abnormal state temporarily.
Unfortunately, we cannot guarantee that IC is not destroyed.
