The power supply circuits operation principle of internet access facility is as follows:
The external the Internet access device is given the power supply of WiFi router main equipment by the operating voltage (can be cell voltage, also can be charger voltage) of internet access facility inside by power supply circuits after the WiFi function is opened at the interface.
After the WiFi function is opened at the interface of internet access facility, VUSB_EN pin in the internet access facility power supply circuits can provide high level signal, Schottky diode D2 ends, and makes the base voltage of N raceway groove triode Q3 reach more than the 0.6V, makes N raceway groove triode Q3 conducting.The G utmost point of metal-oxide-semiconductor field effect transistor Q1, Q2 is pulled down to 0V owing to N raceway groove triode Q3 conducting meeting, Q1, Q2 conducting, and the voltage of VBUS pin output is exactly the voltage of VBAT pin.
After the WiFi function is closed at the interface, the VUSB_EN pin of equipment can provide low level signal, Schottky diode D2 conducting makes the base voltage of N raceway groove triode Q3 have only about 0.3V, N raceway groove triode Q3 ends, the G utmost point of metal-oxide-semiconductor field effect transistor Q1, Q2 can be drawn high by pin VBAT, and metal-oxide-semiconductor field effect transistor Q1, Q2 also end.The path of pin VBUS and pin VBAT is disconnected, and pin VBUS is external output voltage just.
These power supply circuits have also comprised USB line insertion PC and have caused PC to burn out the defencive function of external the Internet equipment.
