Embodiment Construction

[0015] In order to make the objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are exemplified below, and are described in detail as follows in conjunction with the accompanying drawings.

[0016] Certain terms are used in the specification and claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may refer to the same element by different nouns. The present specification and claims do not use the difference in name as a way to distinguish elements, but use the difference in function of the elements as a criterion for distinguishing. The words "comprising" and "including" mentioned throughout the specification and claims are open-ended terms and should be interpreted as "including but not limited to". The word "substantially" means that within an acceptable error range, those skilled in the art can solve the technical prob...

Abstract

An electronic device comprises a power supply interface, a first comparator, a second comparator, a controller, a controller and a second switching circuit. The power supply interface may receive a first input voltage and a second input voltage. The first comparator can compare a first input voltage with a first reference voltage to generate a first comparison voltage. The second comparator can compare a second input voltage with a second reference voltage to generate a second comparison voltage. The controller may generate a first control voltage and a second control voltage according to the first comparison voltage and the second comparison voltage. The first switching circuit can be selectively enabled or disabled according to the first control voltage. The second switching circuit can be selectively enabled or disabled according to a second control voltage.

Description

technical field [0001] The present invention relates to an electronic device, in particular to an electronic device with an automatic detection function. Background technique [0002] In a conventional electronic device, if the alternating current (Alternating Current, AC) power terminal of any charger (Charger) is removed, the removal event cannot be detected quickly, which often leads to misjudgment of the electronic device. In view of this, it is necessary to propose a completely new solution to overcome the problems faced by the previous technology. SUMMARY OF THE INVENTION [0003] In a preferred embodiment, the present invention provides an electronic device that is selectively coupled to a first charger or / and a second charger, and includes: a power supply interface, including a first input port and a second input port , wherein the first input port is used for receiving the first input voltage, and the second input port is used for receiving the second input volta...
