Integrated circuit of improved motorcycle igniter

Abstract

The invention relates to an integrated circuit of an improved motorcycle igniter, comprising a power source anode end, a positive impulse input end, a negative impulse input end, a power source cathode end, an ignition control impulse end, a first constant-current output end, a second constant-current output end and a rotate-speed curve forming end. The positive impulse input end, the negative impulse input end and the rotate-speed curve forming end are input ends; the ignition control impulse end, the first constant-current output end and the second constant-current output end are output ends; the power source anode end and the power source cathode end are connected with a corresponding direct-current power source; the output of the ignition control impulse end can drive an ignition angle needed by installing the motorcycle igniter to ignite, and an ignition advanced angle of the motorcycle igniter can be regulated by regulating the rotate-speed curve forming end. The integrated circuit of the improved motorcycle igniter reduces pins of an igniter integrated circuit by optimizing the traditional igniter integrated circuit, greatly reduces the encapsulation cost of the igniter integrated circuit, is convenient to operate and use and is safe and reliable.

Description

technical field [0001] The invention relates to an integrated circuit, in particular to an improved motorcycle igniter integrated circuit. Background technique [0002] There are three major categories of electrical equipment for motorcycles, namely rectifier and voltage regulator (commonly known as voltage stabilizer), ignition controller (referred to as igniter) and other electronic components, such as audio, flasher, alarm and so on. Among them, the igniter is the most important category. It is a class A component in the motorcycle, and it is of great significance to the quality assurance of the motorcycle and the personal safety of the driver. [0003] There are two types of ignition for motorcycle igniters: capacitive discharge and inductive discharge. They all use the ignition coil to boost the ignition pulse to about 14kV, then add it to the spark plug to generate a discharge spark, ignite the mixed gas, and the gas burns and explodes to generate thrust, so that it c...
