摘要：Embodiments of the present invention provide a thermal protection circuitwhich relates to the field of electronic technologies and can detect temperature ofmultiple locations simultaneously and adjust a preset temperature threshold flexibly,thereby improving system reliability. The thermal protection circuit includes: at least one
temperature sensor, a detection circuit, an execution circuit, a self-locking and triggeringcircuit, a protective temperature regulation circuit, and a power supply circuit. The atleast one temperature sensor converts a temperature signal into an electrical signal andsends the electrical signal to the detection circuit; the detection circuit detects whethertemperature reaches a preset threshold, and sends a turn-off signal to the executioncircuit if the temperature reaches the preset threshold; the execution circuit cuts offpower supply to the system; and the self-locking and triggering circuit maintains, afterthe power supply to the system is cut off, a power-off state of the system until a powerswitch is triggered. The embodiments of the present invention are used for circuitprotection.
