摘要
在对传统汽油机点火电路原理分析和总结的基础上，分析其不足并针对市场需要设计出一款点火角控制精确，一致性好，价格低廉的点火控制芯片。电路设计基于金属氧化物半导体（CMOS）工艺，采用与电源电压和工艺无关的设计，从而提高了产品的稳定性、可靠性和一致性，该电路具备完善的静电释放（ESD）设计，工作电压3～6V，静电流小于2mA，可广泛应用于125mL及以下排量的汽油机中。
On the basis of analyzing traditional motor igniter, a new motor igniter with precise ignition angle control, good consistency and low price has been designed. The circuit design is based on the CMOS technique and the design idea of low pertinence to process and power supply has been introduced to promote its stability, reliability and consistency. This circuit is implemented in a standard CMOS technology with perfect ESD design and can work under a broad range of power supply from 3-5 V with a quiescent current less than 2 mA and can be widely used in motor with air discharge of 125 mL and below.
