... After compulsorily tuning off the output DMOS, when the Amplifier is automatically reset in usual operation and the over current flows continuously, the protection operation is performed again. * The over current protection circuit is a function to avoid the abnormal state like the output short-circuit temporarily. Unfortunately, we cannot guarantee that IC is not destroyed. LV49157V Function image Function image No.A1567-15/30 ...

... Thermal protection circuit The LV49157V 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. ...

... When it is used this function as output power limit, please use the high-precision resistance such as the metal film resistor when precision of the electricity value is necessary. * The value of external PLC resistance R1 please connects more than 3kΩ. * When it is changed a value of external PLC resistance R1, please turn off an amplifier.
