Abstract

The invention discloses a parallel charging circuit and a mobile terminal. The method comprises: a main power management chip, an auxiliary power management chip, a heterogeneous parallel charge controllable switch, and a wireless charging receiving chip, wherein the main power management chip and the auxiliary power management chip One of the power management chips is connected to an external wired charger, and the other power management chip is connected to an external wireless charger through a wireless charging receiving chip; the heterogeneous parallel charge controllable switch is connected to the auxiliary power management chip and the external between the corresponding chargers, and is controlled by the enabling control of the main power management chip. The invention realizes wireless charging and wired charging simultaneously.

Description

technical field [0001] The invention relates to the field of mobile terminal control, in particular to a parallel charging circuit and a mobile terminal. Background technique [0002] In the current wireless charging technology, since the output power of the wireless charger is inconsistent with the charging power of the USB power supply, it cannot be charged at the same time. Among all wireless charging schemes for mobile terminals, wired charging is preferred, and wireless charging is only allowed when there is no wired charging condition. Moreover, the circuit of the mobile terminal has a circuit design that isolates wired charging and wireless charging to protect the circuit behind the interface; at the same time, it prevents the user from inserting the connection line of the USB power supply charging power supply when the mobile terminal is performing wireless charging. , resulting in damage to the internal circuits of the mobile terminal. [0003] However, this desig...
