NCP398FCCT1G

The NCP398 is an overvoltage protection device. It protects VCONN against overvoltages in applications where VCONN is directly derived from the VBUS supply. At power up, the integrated power MOSFET is automatically controlled to reduce inrush current. The IC continuously monitors under voltage, overvoltage and thermal events. In case of overvoltage, a very high speed comparator opens the power MOSFET instantaneously. The part is enabled through the EN pin. A high level on this pin allows forcing off the internal switch and drastically decreases the current consumption of the NCP398 core.
