Over Temperature Protection (OTP)

What is Over Temperature Protection (OTP)?

Over Temperature Protection (OTP) is a safety feature built into power supplies to prevent them from overheating and causing damage to the system they are powering.

When the temperature inside the power supply exceeds a predetermined threshold, OTP will activate and shut down the power supply. The OTP circuitry typically consists of a temperature sensor that is placed inside the power supply, as well as a control circuit that monitors the temperature and controls the power supply's output. When the temperature rises above a certain level, the control circuit will immediately reduce the power output, and if the temperature continues to rise, the power supply will shut down completely. OTP is an important safety feature for power supplies, as overheating can cause damage not only to the power supply but also to the components it is powering. In addition to preventing damage, OTP can also prevent potential safety hazards such as fires and electrical shocks. It is important to note that OTP is not a substitute for proper thermal management within a system. Proper airflow and cooling should still be employed to keep the temperature of the power supply within safe operating limits
