摘要： A thermal protection circuit to protect an electronic device from over-heat comprises a temperature sensor, a hysteresis comparator and a switch circuit. The temperature sensor senses internal temperature of the electronic device and output an internal temperature signal with voltage. The hysteresis comparator outputs a power-off signal when the voltage of the internal temperature signal is lower than a low voltage threshold representing an a determined temperature, or outputs a power-on signal when the voltage of the internal temperature signal is higher than a high voltage threshold representing a restarting temperature. The switch circuit stops transmitting power signals to the electronic device in response to the power-off signal, or continues to transmit the power signals to the electronic device in response to the power-on signal.

摘要： A broadband filter filtering noise over a first conductive wire, a second conductive wire, and a third conductive wire includes a differential-mode filtering circuit connected to both the first conductive wire and the second conductive wire and a common-mode filtering circuit connected to both the first conductive wire and the second conductive wire. The differential-mode filtering circuit includes two inductors and two capacitors for filtering differential-mode noise of different frequencies. The common-mode filtering circuit includes two inductors and six capacitors filtering common-mode noise of different frequencies.
