NX20P5090

NX20P5090 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. 2.
