Embodiment Construction

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0020] see figure 1 , +Vin1 and +Vin2 are two available power sources. A power input two-choice compatible processing circuit of the present invention includes: a first power input, a second power input, a switch signal input, and a power output and a switch signal output for supplying to a functional circuit, the first power input and the switch The signal input is connected to the switch signal output, and the first power input and the second power input are gated and connected to the power output through the first MOS transistor and the second MOS transistor. Through two MOSFETs (both the first MOS tube and the second MOS tube are MOSFETs), the power + Vin1 (the first power input) and the power + Vin2 (the second power input) can be selected as ...

Abstract

The invention discloses a power input either-or compatible processing circuit which comprises a first power input, a second power input, a switching signal input, a power output and a switching signal output, the power output and the switching signal output are provided for a functional circuit, and the first power input and the switching signal input are connected to the switching signal output. The first power input and the second power input are connected to the power output through gating of a first MOS tube and a second MOS tube. According to the processing circuit, the requirement of the OR gate control logic of two-path power supply input gating is met, and the problem of device heating of a circuit adopting a power diode to build an OR gate is avoided at the same time.

Description

technical field [0001] The invention relates to the technical field of power input for new energy vehicles, in particular to a compatible processing circuit for selecting one of two power inputs. Background technique [0002] With the development of new energy vehicle technology, during the update and iteration process of automotive products and components, considering factors such as generalization and cost, it is sometimes necessary to be compatible with multiple other products. The unification and universality of components often require some compatibility processing on the integrated circuit board. The problem that the functional circuit is compatible with two-way power input is solved, and the heat is serious when the power diode is used for power input switch control. Contents of the invention [0003] The invention provides a compatible processing circuit for selecting one of two power inputs, which is used to solve the technical problem that the existing functiona...
