Integrated ignition coil

Abstract

The invention discloses an integrated ignition coil, which comprises an interface module, a power module, an ignition pre-driving module, an ignition driving module, an over-current detection module,an over-temperature detection module, an indicator light and an ignition coil. The interface module is connected with the power module and the ignition pre-driving module; and the power module is further connected with the ignition pre-driving module, the indicator light, the over-current detection module and the over-temperature detection module. According to the integrated ignition coil providedby the invention, the ignition coil can work normally if only a power supply and an ignition signal are introduced, and under the interference of a large external pulse, a drive circuit is automatically filtered; when the ignition coil works abnormally, a protection circuit is automatically started, and the ignition coil back to work normally; and in addition, through the flickering of the ignition indicator light, whether the ignition coil works normally or not can be judged conveniently.

Description

technical field [0001] The invention relates to an ignition coil, in particular to an integrated ignition coil. Background technique [0002] The integrated ignition coils on the existing market are generally single-drive tube direct-drive ignition coils, which do not have large pulse signal protection. When an interfering large pulse signal comes, the ignition coil is basically overcharged and burned out; there is no ignition indicator light , It is impossible to judge whether the ignition coil is working normally intuitively. Contents of the invention [0003] The purpose of the present invention is to provide an integrated ignition coil to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] An integrated ignition coil, including an interface module, a power module, an ignition pre-driver module, an ignition drive module, an overcurrent d...
