基于ATMEGA1281的钝感型电点火具触发器电路设计

Circuit Design of Insensitive Electric Igniter Trigger Based on ATMEGA1281

设计了一种基于ATMEGA1281的钝感型电点火具触发器。该触发器可以控制产生多路用于触发钝感型电点火具的大电流脉冲。在设计中实现了脉冲通道工作状态检查、带载状态检查以及对脉冲电流的实时检测,体现了良好的测试性设计。同时,在设计中设置了多重保护电路,有效提高了触发器的可靠性和安全性。

An insensitive electric igniter trigger based on ATMEGA1281 is designed. The trigger can offermultiplex large current pulse to trigger insensitive electric igniters. In the design, pulse channel operation state in-spection, load state inspection and pulse current inspection in real time are realized and good testability design isshown. And multiple protection circuits are designed to improve the reliability and safety of the trigger effectively.
