Positive Overvoltage
Protection Controller with
Internal Low R
ON
NMOS FET
and Status FLAG
The NCP348 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
necessary, reducing the system cost and the PCB area of the
application board.
The NCP348 is able to instantaneously disconnect the output from
the input, due to integrated Low R
ON
Power NMOS (65 m ), if the
input voltage exceeds the overvoltage threshold (OVLO) or
undervoltage threshold (UVLO).
At powerup (
EN
pin = low level), the V
out
turns on 50 ms after the
V
in
exceeds the undervoltage threshold.
The NCP348 provides a negative going flag (
FLAG
) output, which
alerts the system that a fault has occurred.
In addition, the device has ESDprotected input (15 kV Air) when
bypassed with a 1.0 F or larger capacitor.
