... 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. ...
