Note: The above is an example of thermal shutdown circuits although there are some differences from the actual internal
circuit.
Thermal Shutdown Operation
The thermal shutdown circuit compares the voltage of the heat sensitive element (diode) with the reference voltage and
shuts off the drive circuit at a certain temperature to protect the IC chip from overheating.
