Operation
positive voltage, up to 28 V. A low R
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 t

overtaking undervoltage UVLO (Figure 3). The NCP349
provides a FLAG output, which alerts the system that a fault
has occurred. A t
output (Figure 3) is added between output signal rising up
and to FLAG signal rising up. FLAG pin is an open drain
output.
