摘要： Disclosed are an electrostatic discharge circuit and a method for preventing malfunctions of an integrated circuit due to a reverse connection of a power source. The electrostatic discharge circuit includes at least one MOSFET for providing an electrostatic discharging current path, and a control circuit coupled to the at least one MOSFET. When an external power supply is reversely connected, the control circuit is configured to change a potential of a body of at least one MOSFET, such that the at least one MOSFET is turned off, thereby preventing the integrated circuit from malfunctioning caused by a current generated by the reverse connection of the external power source flowing through the at least one MOSFET.

摘要： There is provided an electronic device having Bluetooth communication function. The electronic device confirms whether the received signal power is larger than a power threshold within an interval of 72 microseconds every time an RF receiver is turned on in the receive slot so as to determine whether to continuously keep the RF receiver being turned on or to turn off the RF receiver to save power.
