Embodiment Construction

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like figure 1 It is a schematic structural diagram of a reset circuit provided by an embodiment of the present invention; the reset circuit includes: at least one switch branch, a control branch and a delay branch;

[0038] One end of the switch branch is connected to the reset trigger end, and the other end is connected to one end of the control branch;

[0039] The other end of the control branch is connected to one end of the delay branch;

[0040] The other end of the delay branch is the system control end.

[0041] Based on the above examples, as figure 2 and image 3 shown is a reset circuit diagram provided by an embodiment of the present invention; when the reset circuit includes two switch branches, the reset circuit incl...

Abstract

The invention discloses a reset circuit and an electronic device equipped with same. The reset circuit comprises at least one switch branch, a control branch, and a time delay branch. One end of each switch branch is connected with a reset trigger end. The other end of each switch branch is connected with one end of the control branch. The other end of the control branch is connected with one end of the time delay branch. The other end of the time delay branch is connected with a system control end. The reset circuit uses discrete devices to achieve the at least one switch branch, the control branch, and the time delay branch so as to reset an electronic product in a time delayed manner. Not only is design cost reduced, but also the reset circuit designed through the discrete devices is completely powered off and consumes no electric power when an electronic product is not reset.

Description

technical field [0001] The present invention relates to the technical field of power electronics, in particular to a reset circuit and an electronic device having the circuit. Background technique [0002] With the continuous development of power electronic technology and the continuous improvement of production technology, various electronic devices emerge in an endless stream. At present, more and more electronic products tend to be smaller and lighter in size and weight, which makes it more and more difficult to disassemble and repair. Especially when the product crashes and cannot be reset, the product will be unusable. However, in the prior art, a dedicated reset IC is usually used to realize the reset function, such as a reset IC with pulse output; the reset IC can simultaneously realize shutdown or reset and effectively distinguish reset from other operation functions without adding peripheral circuits. [0003] However, in the process of designing the electronic de...
