NCP347MTAETBG

The NCP347 is able to disconnect the systems from its output pin in case wrong input operating conditions are detected. The system is positive overvoltage protected up to +28 V. Due to this device using internal NMOS no external device is necesary reducing the system cost and the PCB area of the application board. The NCP347 is able to instantaneously disconnect the output from the input due to integrated Low Ron Power NMOS (65 mO if the input voltage exceeds the overvoltage threshold (5.63 or 5.9 or 7.2 V) or undervoltage threshold of 2.95 V (UVLO). At powerup (EN(BAR) pin = low level) the Vout turns on 50 ms after the Vin exceeds the undervoltage threshold. The NCP347 provides a negative going flag(FLAG(BAR)) output which alerts the system that a fault has occurred. In addition the device has ESD-protected input (15 kV Air) when bypassed with a 1.0 F or larger capacitor.
