产品描述

The NX20P5090 is an advanced 5.0 A Uni-directional power switch for USB PD. It includes undervoltage lockout, over voltage lockout, reverse current protection and over-temperatureprotection circuits, it is designed to automatically isolate the power switch terminalswhen a fault condition occurs. Both VBUS and VINT pin have 29 V tolerance in shutdownmode, two NX20P5090s can be used in parallel to support dual power inputs connecting tosame charging circuit.

The device has a default 23 V over voltage protection threshold, and the OVP thresholdcan be adjusted by using external resistors on OVLO pin. A 15 ms debounce time isdeployed every time before the device is switched ON, followed by a soft start to limitthe inrush current.

Designed for operation from 2.5 V to 20.0 V, it is used in USB PD power domain isolationapplications to offer essential protection and enhance reliability.

NX20P5090 is offered in a small 15 bumps 1.6 × 2.6 mm, 0.5 mm pitch WLCSP package.
