High voltage USB PD power switch

Rev. 1 — 14 October 2016

Product data sheet

1. General description

The NX20P5090 is an advanced 5 A unidirectional power switch for USB PD. It includes

under voltage lockout, over voltage lockout, reverse current protection and

over-temperature protection circuits. It is designed to automatically isolate the power

switch terminals when a fault condition occurs. Both VBUS and VINT pins have 29 V

tolerance in shutdown mode. Two NX20P5090 chips can be used in parallel to support

dual power inputs connecting to the same charging circuit.

The device has a default 23 V over voltage protection threshold, and the OVP threshold

can be adjusted by using an external resistor divider on OVLO pin. A 15 ms de-bounce

time is deployed every time before the device is switched ON, followed by a soft start to

limit the inrush current.

Designed for operation from 2.5 V to 20 V, it is used in USB PD power control applications

to offer essential protection and enhance system reliability.

NX20P5090 is offered in a small 15 bump, 2.56 x 1.54 x 0.555 mm WLCSP package.
