The IC provides full protection functions. The following table summarizes these protection functions.

During operation, the VCC voltage is continuously monitored. In the case of undervoltage or overvoltage, the IC
is reset and the main power switch is then kept switched off. Once the VCC voltage falls below the threshold

During off-time of the power switch, the voltage at the zero-crossing pin is monitored for output overvoltage
detection. If the voltage is higher than the preset threshold
time.
If the junction temperature of IC exceeds 140 °C, the IC enters into the autorestart mode.
If the voltage at the current sensing pin is higher than the preset threshold V
switch, the IC is latched off. This is short-winding protection.
During latch-off protection mode, when the VCC voltage drops to 10.5 V, the startup cell is activated and the VCC
voltage is charged to 18 V; then the startup cell is shut down again and repeats the previous procedure.
There is also a maximum on-time limitation applicable to the ICLS8082G. Once the gate voltage is high for longer
