Abstract

The invention discloses a method and a device for charging detection on USB type C equipment. The method comprises steps that a voltage of a configuration signal of the USB type C equipment is acquired; whether the voltage of the configuration signal surpasses a first threshold is detected; if the voltage of the configuration signal is detected to surpass the first threshold, high voltage charging for the USB type C equipment is forbidden; if the voltage of the configuration signal is detected to be lower than the first threshold, high voltage charging for the USB type C equipment is permitted. The method is advantaged in that a technical problem that the configuration signal can be easily damaged during high voltage charging for the USB type C equipment in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular, to a charging detection method and device for a USB type C device. Background technique [0002] With the continuous update of USB devices, USB type C devices, which are upgrade devices of USB type A devices, have appeared on the market. In order to make the two devices compatible, there are two types of USB type A devices in related technologies. The cable of the device, in the standard cable, the configuration signal CC of the USB type C device interface is connected to the signal Vbus of the transmission power through a 56K resistor, such as figure 1 As shown, while the configuration signal CC is directly connected to the signal Vbus of the transmission power in a non-standard cable, such as figure 2 shown. In actual use, the USB type C device interface will be directly connected to the USB typeC device, and the USB type A device interface will be directly connect...
