CXPR78109是一种创新的过电压保护器，可用于单向或双向模式，只需改变外部连接。在双向模式下，集成在CXPR78109中的开关可以通过反向阻断功能关闭，不再使用体二极管。CXPR78109由一个电荷泵、一个可配置的功率MOSFET、一个电压基准、一个栅极驱动器以及一些逻辑和保护模块组成。CXPR78109对输入浪涌的反应非常快，能在0.5us内关闭开关，并能承受高达20V的电压尖峰

产品概述 返回TOP
CXPR78109 is an innovative over voltage protector which can be used either in unidirectional or bidirectional mode, by only change the external connecting. In bidirectional mode, the switch integrated in CXPR78109 can shut off with the reverse blocking function, no body diode anymore. CXPR78109 consists of a charge pump, a configurable power MOSFET, a voltage reference, a gate driver and some logics and protection modules. CXPR78109can react to a input surge very fast and shut off the switch in 0.5us and stand the voltage spike as high as 20V. CXPR78109is in SOT23-6 package
