Abstract

The embodiment of the invention provides a trigger circuit and charging equipment. The trigger circuit is arranged in the charging equipment. The trigger circuit comprises an MOS switch, a first resistor and a second resistor, wherein a drain electrode of the MOS switch is connected with a boosting device in the charging equipment through the second resistor, a grid electrode of the MOS switch isconnected with the first resistor, the first resistor is grounded, a PE2.0 control signal is accessed into the grid electrode of the MOS switch, and a source electrode of the MOS switch is grounded; and the MOS switch is closed under the control of the PE2.0 control signal, so that the boosting device is used for boosting the voltage into preset voltage. Through the embodiment, the trigger circuitcan be used for realizing the boosting function of a charger with PE2.0 protocol.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of charging, in particular to a trigger circuit and a charging device. Background technique [0002] The efficiency of the wireless charging transmitter is relatively high at high voltage. For example, the input of 9V is higher than that of 5V. At present, the maximum input current of the mainstream wireless charging transmitter solution is 2A. If the input voltage is 5V, because of the efficiency problem, the mobile phone should support 2A. The high charging current cannot be realized, and the maximum efficiency of the whole scheme is less than 70% at present. Therefore, only by raising the input voltage can the 2A charging current of the mobile phone be satisfied. [0003] The existing technology is generally based on the trigger circuit of the QC2.0 protocol to trigger the booster in the charger to increase the output voltage of the charger to 9V or 12V, but this cannot be done ...
