Product details
Overview
PI5USB31213AXEAEX from Diodes Incorporated is a USB 3.1 Gen2 10Gbps dual-role port controller with integrated 2:1 bidirectional mux/demux, CC pin detection logic, VCONN power switch, and I²C/pin-selectable control. It manages Type-C connector orientation, host/device/Dual-Role Port (DRP) mode auto-configuration, and supports 2.7V–5.5V supply across –40°C to +85°C. Used in notebooks, docking stations, and mobile phones for high-speed USB data routing and power role negotiation.
For engineers reviewing the PI5USB31213AXEAEX datasheet, PI5USB31213AXEAEX pinout, PI5USB31213AXEAEX application, or PI5USB31213AXEAEX equivalent, key selection criteria include USB 3.1 Gen2 signal integrity at 10Gbps, CC-based DRP auto-configuration, VCONN over-voltage/over-current protection, dual control interface (I²C vs. PORT pin), and support for Default/1.5A/3A current modes.
Technical Context
The PI5USB31213AXEAEX implements a dual-channel, 10Gbps differential mux/demux path between USB 3.1 Gen2 controller and Type-C receptacle, preserving signal integrity via low insertion loss (< –1.2dB @ 5GHz) and high return loss (>12dB). Its embedded CC logic detects plug orientation and negotiates power roles without external microcontroller intervention.
It integrates precision CC pull-up/pull-down resistors (5.1kΩ ±1%), programmable current sources for Rp/Rd, VCONN power switch with OVP/OCP, and interrupt-driven I²C register access (7-bit slave address 0x48 or 0x49 per ADDR pin). Pin control mode uses PORT and ADDR pins for static mode selection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C dual-role port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TUSB1146IRGET | Single-lane USB 3.1 Gen1 (5Gbps); no integrated VCONN switch or CC logic - requires external components for DRP | Suitable for cost-optimized Gen1-only docks without active cable support | Select when Gen2 speed and integrated VCONN are not required |
| NXP PTN5150AAY | USB 3.1 Gen2 capable but lacks integrated mux - functions as CC logic + power switch only; external mux needed | Used where separate high-speed signal routing is handled by discrete switches or SoC PHY | Select when system already includes a Gen2 mux and only CC/VCONN control is needed |
Compared with TUSB1146IRGET and PTN5150AAY, the PI5USB31213AXEAEX uniquely combines Gen2 10Gbps mux, full DRP hardware automation, and VCONN power management in one package-reducing BOM count by ≥4 discrete components and eliminating firmware dependency for basic Type-C role negotiation.

FAQ
What USB specifications does the PI5USB31213AXEAEX support?
The PI5USB31213AXEAEX fully supports USB 3.1 Gen2 (10Gbps) data transfer, USB Type-C™ 1.4 specification for connector orientation and DRP behavior, and USB Power Delivery 3.0 signaling via CC pin detection. It complies with USB-IF electrical requirements for insertion loss, return loss, and crosstalk up to 10GHz.
How does the PI5USB31213AXEAEX handle Type-C plug orientation detection?
It uses internal analog comparators on CC1 and CC2 pins to detect voltage levels from the connected plug's Rp/Rd resistors. Based on which CC line shows a valid voltage (typically ~0.4V or ~0.8V), the device automatically determines plug orientation and configures the mux path accordingly-no software or external logic required.
Can the PI5USB31213AXEAEX operate without an I²C host controller?
Yes. When ADDR pin is grounded and PORT pin is set, the device operates in pin-control mode: PORT selects host/device/DRP mode at power-up, and all configuration-including current mode-is fixed. I²C is optional for dynamic reconfiguration during runtime.
What protection features are built into the VCONN output?
The VCONN output includes over-voltage protection (OVP) that disables the switch if voltage exceeds 6.5V, and over-current protection (OCP) that limits output to 220mA and latches off upon fault. Both protections are hardware-based and require no external components or configuration registers.
