NCP398 Datasheet, PDF (1/12 Pages) ON Semiconductor – USB Type-C VCONN Overvoltage Protection IC

NCP398
USB Type-C VCONN
Overvoltage Protection IC
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
undervoltage, 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.
