描述 Description

The NX5P2090 is an advanced power switch for USB OTG applications. It includesunder-voltage and over-voltage lockout, over-current, over-temperature, reverse bias andin-rush current protection circuits. These are designed to automatically isolate a VBUSOTG voltage source from a VBUS interface pin when a fault occurs. The device featurestwo power switch terminals, one input (VINT) and one output (VBUS); a current limit input(ILIM) for defining the over-current and in-rush current limit; a voltage detect output(VDET) to monitor the voltage level on VBUS; an open-drain fault output (FAULT) toindicate when a fault condition has occurred and an enable input (EN) to control the stateof the switch. When EN is set LOW the device enters a low-power mode, disabling allprotection circuits except the under-voltage lockout. The low-power mode can be enteredat anytime unless 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.
