MC3423P1電路保護的TVS-混合技術規(guī)格書PDF中文資料

MC3423P1屬于電路保護的TVS-混合技術。由安森美半導體公司制造生產的MC3423P1TVS - 混合技術混合技術 TVS（瞬態(tài)電壓抑制器）產品族中的產品屬于過壓保護產品，其中結合了基于多種技術的保護機制，例如串聯(lián)連接的 MOV（金屬氧化物壓敏電阻）和 GDT（氣體放電管），旨在同時獲得低漏電流和自恢復箝位工作特性。

This overvoltage protection circuit (OVP) protects sensitive electronic circuitry from overvoltage transients or regulator failures when used in conjunction with an external “crowbar” SCR. The device senses the overvoltage condition and quickly “crowbars” or short circuits the supply, forcing the supply into current limiting or opening the fuse or circuit breaker. The protection voltage threshold is adjustable and the MC3423 can be programmed for minimum duration of overvoltage condition before tripping, thus supplying noise immunity. The MC3423 is essentially a “two terminal” system, therefore it can be used with either positive or negative supplies.
