NCP361 is able to disconnect the system from its output pin in case wrong VBUS operating conditions are detected. The system is positive overvoltage protected up to +20 V. Thanks to the integrated PMOS FET no external device is necessary reducing the system cost and the PCB area of the application board. NCP361 is able to instantaneously disconnect the output from the input if the input voltage exceeds the overvoltage threshold (OVLO).Thanks to an overcurrent protection the integrated PMOS is turning off when the charge current exceeds current limit (see options in ordering information). NCP361 provides a negative-going flag (FLAG) 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.
