一.产品概述8Oi嘉泰姆

  CXPR7885 is a main rail current detection and over current protection IC. It includes a current shunt comparator and shutdown comparator with a precision shunt regulator like 8Oi嘉泰姆
    The rail current detection gain can be adjusted with three external resistors. The regulator output CSO pin is connected to a shutdown comparator for driving a protection circuit like a photo-coupler to shutdown the primary side PWM IC when over current occurs.8Oi嘉泰姆
    The voltage shunt regulator has a 2.5V reference for switching power supply secondary output voltage feedback.8Oi嘉泰姆
CXPR7885 can be used for OCP and output voltage feedback function with few external parts. It is suitable for application in secondary main rail power supply of SPS or isolated fly-back DC-DC converter.  8Oi嘉泰姆
