Abstract

The invention provides a power supply switching hardware circuit, a power supply circuit and electronic equipment, and the power supply switching hardware circuit comprises a first switching circuit which is connected between an internal power supply interface and a complete machine power supply interface, and enables a power supply path between an internal power supply and a complete machine to be connected after the internal power supply is turned on, thereby achieving the complete machine power supply of the internal power supply; a second switching circuit which is connected between the external power supply interface and the complete machine power supply interface, and enables a power supply access between the external power supply and the complete machine to be connected after the external power supply is switched on, so the complete machine power supply of the external power supply is realized; and a switching control circuit which is connected between the first switching circuit and the second switching circuit and used for controlling connection and disconnection of the first switching circuit so as to realize isolation of an external power supply and an internal power supply. A pure hardware circuit is adopted to solve the problem of work switching logic conflict when an external power supply and an internal power supply of equipment are simultaneously switched on, and response is quick.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply switching hardware circuit, a power supply circuit and electronic equipment. Background technique [0002] With the improvement of people's living standards, the application of portable devices is becoming more and more extensive. Portable devices are generally equipped with rechargeable power modules inside. Supply power to the device to meet the operation of the device; in indoor and other application scenarios, the external power supply can be used to supply power to the device to meet the operation of the device, and at the same time charge the internal rechargeable power module to meet the requirements of recycling. However, when the external power supply and the internal power supply of the portable device are turned on at the same time, there will be a work switching logic conflict. [0003] Therefore, how to manage the working modes of the two modul...
