NX5P2190UK: Logic controlled high-side power switch
The NX5P2190 is an advanced power switch with adjustable current limit. It includes
under-voltage and over-voltage lockout, over-current, over-temperature, reverse bias and
in-rush current protection circuits. These circuits are designed to isolate a voltage source
from a VBUS interface pin automatically when a fault occurs. The device features two
power 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) indicates
when a fault condition occurs. An enable input (EN) controls the state of the switch. When
EN is set LOW the device enters a low-power mode, disabling all protection circuits
except the under-voltage lockout. The low-power mode can be entered at anytime unless
the over temperature protection circuit has been triggered.
Designed for operation from 3 V to 5.5 V, the NX5P2190 is a complete solution for power
domain isolation and protection applications. The enable input includes integrated logic
level translation making the device compatible with lower voltage processors and
controllers.
