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
