Product details

What this N-channel load switch does on the board

The NX30P0121UKZ is a single-output, general-purpose N-channel power switch from NXP's NX3 series, packaged in a 12-bump WLCSP (1.65 x 1.25 mm).

Protection set and operating envelope

Built-in fault protection covers current limiting (adjustable), over-temperature shutdown, over-voltage lockout, and UVLO — so the switch can handle a hot-plug event or a brief output short without needing external clamp diodes. The input supply (Vcc/Vdd) is not required: the part is self-powered from the load rail, which simplifies the BOM for a basic power-rail switch. The 1:1 input-to-output ratio means it passes the full input voltage to the load when enabled — no internal regulation, just a pass-FET.

Package, mounting, and lifecycle

Lifecycle status is Active per NXP, with ROHS3 compliance confirmed.
