可双向关断过压保护点可调高耐压低内阻快速响应CXPR78109高侧过压保护(OVP) IC，只需改变外部连接即可单向或双向使用。在双向模式下，集成中的开关可通过反向阻断功能关闭不再使用体二极管。

   产品概述 返回TOPPl9嘉泰姆

    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
