产品描述

The NX5P2190 is an advanced power switch with adjustable current limit. It includesunder-voltage and over-voltage lockout, over-current, over-temperature, reverse bias andin-rush current protection circuits. These circuits are designed to isolate a voltage sourcefrom a VBUS interface pin automatically when a fault occurs. The device features twopower switch terminals, one input (VINT) and one output (VBUS). A current limit input(ILIM) defines the over-current and in-rush current limit, and a voltage detect output(VDET) monitors the voltage level on VBUS. An open-drain fault output (FAULT) indicateswhen a fault condition occurs. An enable input (EN) controls the state of the switch. WhenEN is set LOW the device enters a low-power mode, disabling all protection circuitsexcept the under-voltage lockout. The low-power mode can be entered at anytime unlessthe over temperature protection circuit has been triggered.

Designed for operation from 3 V to 5.5 V, the NX5P2190 is a complete solution for powerdomain isolation and protection applications. The enable input includes integrated logiclevel translation making the device compatible with lower voltage processors andcontrollers.
