      CXPR78105 is a 36V surge voltage over voltage protector (OVP) integrated with a 300V 13.2V TVS diode, which has a very low 33mohm on resistance. It can be used as an OVP device or a high voltage switch at power input port. CXPR78105 consists of a charge pump, a configurable power MOSFET, a voltage reference, a gate driver, some logics, protection modules and a 300V 13.2V TVS diode. CXPR78105can react to aninput surge very fast and shut off the switch in less than 0.1us and stand the voltage spike as high as 36V. CXPR78105is in DFN3x3-12 package
