PTN5110NHQZ

Overview

The PTN5110NHQZ is a USB Type-C PHY IC designed to implement the Type-C Port Controller (TCPC) specification Revision 2.0 version 1.0. It manages the physical layer signaling for USB Power Delivery (PD) and Type-C cable attachment detection, offloading these complex tasks from a host microcontroller or EC. This specific variant is configured for Dual Role Power (DRP) at power-on reset, starting in the Sink role.

Why Choose This Part

It features an extremely small footprint in a 2.6mm x 2.6mm HX2QFN16 package with a low sleep current of 40uA for power-sensitive mobile applications. The hardware-based TCPC implementation ensures standard-compliant timing for critical PD functions, while the 25V-tolerant VBUS pins provide robust protection against electrical overstress.

Applications

Getting Started

Integration requires an I2C host controller running a TCPM (Type-C Port Manager) software stack to handle policy engine logic. Engineers should reference NXP's technical documentation for the PTN5110 to map the EN_SNK and EN_SRC pins to external load switches or power management ICs. Development can be accelerated using NXP's USB-C hardware evaluation kits that feature the PTN5110 family.
