PTN3222GMJ

The PTN3222GMJ is a high-speed USB Type-C™ port protection switch from NXP Semiconductors. Designed for USB 3.1/3.2 Gen 1/2 applications, it provides ESD protection, overvoltage protection (OVP), and configurable current limiting for Type-C ports.
Key features:
- Supports 10 Gbps data rates (USB 3.2 Gen 2).
- ±8 kV ESD protection (IEC 61000-4-2).
- Adjustable current limit (0.5 A to 3 A) via external resistor.
- Low on-resistance (80 mΩ typical) for minimal signal loss.
- Automatic power role swapping (supports USB PD).
Applications include laptops, tablets, docking stations, and USB-C hubs. The PTN3222GMJ ensures robust protection while maintaining signal integrity in high-speed USB-C systems.
Package: 20-pin HVQFN (3.5 × 4.5 mm).
