NCP362 Datasheet, PDF (1/16 Pages) ON Semiconductor – USB Positive Overvoltage and Overcurrent Protection with TVS for VBUS and Low Capacitance ESD Diodes for Data

NCP362
USB Positive Overvoltage
and Overcurrent Protection
with TVS for V_BUS and Low
Capacitance ESD Diodes for
Data
The NCP362 disconnects systems at its output when wrong VBUS
operating conditions are detected at its input. The system is positive
overvoltage protected up to +20 V, overcurrent protected up to
750 mA, and receives protection from ESD diodes for the high speed
USB data and V_BUS lines. Thanks to an integrated PMOS FET, no
external device is necessary, reducing the system cost and the PCB
area of the application board.
The NCP362 is able to instantaneously disconnect the output from
the input if the input voltage exceeds the overvoltage threshold
OVLO. Thanks to an overcurrent protection, the integrated PMOS
turns off when the charge current exceeds the current limit (see
options in ordering information).
The NCP362 provides a negative going flag (FLAG) output, which
alerts the system that voltage, current or overtemperature faults have
occurred.
In addition, the device integrates ESD diodes for V_BUS and data
lines which are IEC61000−4−2, level 4 compliant. The ESD diodes
for D+ and D− are compatible with high speed USB thanks to an ultra
low capacitance of 0.5 pF.
