Operation
The NCP348 provides overvoltage protection for
positive voltage, up to 28 V. A Low R DS(on) NMOS FET
protects the systems (i.e.: charger) connected on the Vout
pin, against positive overvoltage. At powerup, with EN pin
= low, the output is rising up 50 ms after the input
overtaking undervoltage UVLO (Figure 3). The NCP348
provides a FLAG output, which alerts the system that a fault
has occurred. A 50 ms additional delay, regarding
available output (Figure 3) is added between output signal
rising up and to FLAG signal rising up. FLAG pin is an open
drain output.
