 本发明的实施方式
下面对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
参见附图1与附图2所示，附图1为点火驱动模块的电路结构框图，附图2为点火驱动电路的典型应用示意图。一种性能稳定、功能可靠的点火驱动电路，包括点火驱动模块、与模块信号输出端相连接的三极管，三极管的基极与模块信号输出端相连接、集电极连接有点火线圈。三极管的发射级通过感测电阻接地，点火驱动模块设置有感测电压输入端，感测电压输入端连接于三极管的发射级。点火线圈包括初级线圈和次级线圈，所述初级线圈的一端与三极管的基极相连接，另一端与电压输入端相连接。
点火驱动模块（CIM1001）包括模块信号输入端、电压输入端和模块信号输出端、与模块信号输入端相连接的比较器、与所述比较器相连接的最大停留时间计时模块、与比较器相连接的逻辑判断模块、与逻辑判断模块相连接的绝缘栅双极型晶体管；逻辑判断模块接收最大停留时间计时模块和比较器的信号判断是否启动绝缘栅双极型晶体管，所述绝缘栅双极型晶体管输出端与模块信号输出端相连接。
点火驱动模块还包括下拉电流输入端，下拉电流输入端与模块信号输入端分别连接比较器的两个输入端，比较器与下拉电流输入端之间设置有电流缓冲器。
点火驱动模块还包括与比较器的输出端相连接的峰值过滤器，正负峰值小于预设时间Ts的输入被峰值过滤器过滤。
点火驱动模块还包括停留时间输入端，停留时间输入端与最大停留时间计时模块相连接，通过对停留时间电容器的设置可以改变最大停留时间，停留时间输入端为停留时间电容器，最大停留时间计时模块与停留时间输入端之间设置有软关闭开关，软关闭开关的一端与绝缘栅双极型晶体管相连接，当软关闭开关开启时，绝缘栅双极型晶体管被关闭。
点火驱动模块（CIM1001）设计用于直接驱动点火IGBT并控制线圈的电流和火花事件。线圈电流通过输入引脚控制。当单端输入被驱动到高电平时，CIM1001的输出被启用以打开IGBT并开始对线圈充电。CIM1001将根据RA线上的编程电流将电流（IIN）输入到输入引脚中。其特点包括：支持地面移动干扰抑制的单端输入；信号线输入缓冲器；输入峰值滤波器；从点火或蓄电池线路操作 ；地面偏移公差：-1.5 V至16 V；可编程最大停留时间；可编程输入下拉电流；通过Vsense引脚控制IGBT限流；软关机后闭合的最大时间；符合SOP-8包装和RoHS。
CIM1001中包含一个最大停留时间计时器，如果输入保持激活时间超过编程时间，该计时器将关闭IGBT。输入峰值滤波器抑制持续时间小于7微秒的单端输入信号。这个时间间隔可以通过一个外部电容器来修改。当超过最大停留时间时，CIM1001将进入软关闭（SSD）模式，在这个模式下，通过降低IGBT的栅极电压来缓慢降低三极管的集电极电流、从而使得线圈放电，以抑制火花事件。在充电期间，CIM1001还将限制IGBT的集电极电流至IC（LIM）。这又是通过点火IGBT发射极引线中的感测电阻实现的，该感测电阻将信号输入到CIM1001的Vsense管脚。
参见附图3所示，附图3为点火驱动模块的示意图。CIM1001是一款先进的点火IGBT控制IC，可在SOP8封装或模具销售中使用。这种功能齐全的智能点火IGBT驱动器在点火驱动器的尺寸和系统性能非常重要的“通电线圈”应用中尤其有利。

功能描述
1、 单端输入信号的输入和峰值滤波器
当输入信号电压达到VInh时，将打开IGBT对线圈充电。当输入电压低于VINL时，通过IGBT的线圈电流将被关闭。如果CIM1001在SSD模式下运行，则输入信号控制被禁用。在SSD序列之后，输入控制将在输入达到有效低值后重新启用。输入线上小于tspike持续时间的正负峰值将被过滤掉，并且不会打开/关闭IGBT。
2、 最大停留时间和软关机(SSD）
参见附图4至附图7，附图4为点火驱动电路的驻留时间和软关机（SSD）关系示意图，附图5为点火驱动电路的信号输入电流与IRA电流关系示意图，附图6为点火驱动电路的软关机转换速率示意图，附图7为点火驱动电路的CSSD电容器与最大停留时间的关系示意图。当IGBT打开时，根据外部CSSD电容器的值启动延迟计时器。如果在时间tdmax之后没有收到有效的下降沿，IGBT将缓慢关闭。线圈电流不会超过典型的1.2A/ms的转换率。如果在时间tdmax之后收到有效的下降沿，则边缘将被忽略，软关机将完成。在检测到有效上升沿之前，不能打开IGBT。如果CSSD电容器的值小于2.2nF或CSSD插脚对地短路，则最大停留时间和SSD功能将被禁用（即直接进入硬关机（HSD）模式）。只有CIM1001提供SSD功能。
