描述 Description

The NX5P1100 is an advanced power switch and ESD-protection device for USB OTGapplications. It includes under voltage and over voltage lockout, over-current,over-temperature, reverse bias and in-rush current protection circuits. These circuits aredesigned to isolate a VBUS OTG voltage source from a VBUS interface pin automaticallywhen a fault condition occurs. The device features two power switch terminals, one input(VINT) and one output (VBUS). It has a current limit input (ILIM) for defining theover-current and in-rush current limit. A voltage detect output (VDET) is used to determinewhen VINT is in the correct voltage range. An open-drain fault output (FAULT) indicateswhen a fault condition has occurred, and an enable input (EN) controls the state of theswitch. When EN is set LOW the device enters a low-power mode, disabling all protectioncircuits except the undervoltage lockout. The low-power mode can be entered at anytimeunless the over temperature protection circuit has been triggered.
Designed for operation from 3 V to 5.5 V, it is used in power domain isolation applicationsto protect from out of range operation. The enable input includes integrated logic leveltranslation making the device compatible with lower voltage processors and controllers.
