目录产品概述 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产品特点 返回TOP Unidirectional and Bidirectional configurable Input OVP with 0.1us reaction time Input standoff voltage up to 20V 10mohm Rdson in Unidirectional mode 40mohm Rdson in Bidirectional mode Protection voltage programmable by Vfb=1.26V SCP and OTP 应用范围 返回TOP All electronic devices with input DC power plug 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ | |||||||||||||||||||||||||||||||||||||||||||||
