Abstract
This document discusses, among other things, a discharge circuit for a USB connector configured to discharge a voltage of a pin (e.g., a VBUS pin) of the USB connector. The discharge circuit can include a discharge load to discharge the voltage of the pin; a first control circuit to adjust the magnitude of the discharge load during discharging, such that power consumption generated by the discharge load meets a first preset condition and a discharge time is within a first preset range, the first preset condition indicating that the generated power consumption does not trigger Over Temperature Protection (OTP); and a second control circuit to detect whether the voltage of the pin is changed based on a reference voltage during discharging and adjust the magnitude of the discharge load in response to the change, such that a slew rate of the voltage of the first pin is within a second preset range.
