When the voltage across the temperature sensor 202 rises to exceed the regulated value of the zener diode D1, the zener diode D1 can stabilize the voltage across the temperature sensor 202 to a regulated range, so as to avoid the temperature sensor 202 from being damaged. In some embodiments, zener diode D1 may clamp the voltage of temperature sensor 202 to a safe range, protecting temperature sensor 202, and improving circuit safety.
