Abstract:
1. An over-thermal protection device, adapted to a hot plug electronic device, the over-thermal protection device comprising: a temperature sensor, having a predetermined temperature established therein, for sensing a present temperature of the hot plug electronic device, and outputting a normal signal when the present temperature does not exceed the predetermined temperature, and conversely outputting an over-thermal signal; and a latch unit, coupled to the temperature sensor, for receiving the normal/over-thermal signal and an initial signal, and accordingly controlling a voltage regulator of the hot plug electronic device to normally supply power to an operation circuit of the hot plug electronic device, or stop supplying the power to the operation circuit, wherein the hot plug electronic device comprises at least one of a USB (Universal Serial Bus) hot plug electronic device, a SATA (Serial Advanced Technology Attachment hot plug electronic device and a PCIE (Peripheral Component Interconnect Express) hot plug electronic device.
