1. A temperature sampling device, comprising:
a temperature measurement unit with a measurement end, configured to change a resistance value of the temperature measurement unit under influence of a change of an ambient temperature of a circuit to be protected; and
a signal processing unit, including at least a feedback circuit, the signal processing unit coupled to the measurement end, and configured to limit a measurement signal in the temperature measurement unit influenced by the change of the resistance value, and to output a temperature sampling signal corresponding to the change of the resistance value,
wherein the temperature sampling signal is generated under a condition of the measurement signal being limited, and wherein, the temperature sampling signal is configured to be transmitted to a temperature protection device.
