NX5P2553GU:Precision adjustable current-limited power switch

The NX5P2553 is a precision adjustable current-limited power switch. The device includes under voltage lockout, over-current, over-temperature, and reverse bias protection circuits designed to automatically isolate the switch terminals when a fault condition occurs. The device features two power switch terminals, one input (VIN) and one output (VOUT); a current limit input (ILIM) for defining the over-current limit; an open-drain fault output (FAULT) to indicate when a fault condition has occurred and an enable input (EN) to control the state of the switch.

The over-current limit threshold can be programmed to between 85 mA and 1.8 A using an external resistor between the ILIM and GND pins. The device has built in soft start. This feature controls the output rise time, minimizing current surges when the switch is enabled.

Designed for operation from 2.5 V to 5.5 V, it is used in power domain isolation applications to protect from out of range operation. The enable input includes integrated logic level translation making the device compatible with lower voltage processors and controllers.
