Product details
Overview
PI5USB30216AXUAEX from Diodes Incorporated (formerly Pericom Semiconductor) is a USB Type-C™ plug-in detector IC that identifies cable orientation, port role (host/device/dual-role), and charging capability via CC1/CC2 channel analysis. It supports 2.7V–5.5V supply, operates from –40°C to +85°C, delivers 80µA host pull-up current in default mode, and integrates precision resistors and current sources for full compliance with USB Type-C Specification 1.1. Used in mobile phones and docking stations for automatic port configuration.
For engineers reviewing the PI5USB30216AXUAEX datasheet, PI5USB30216AXUAEX pinout, PI5USB30216AXUAEX application, or PI5USB30216AXUAEX equivalent, key selection criteria include CC detection accuracy, dual-mode control (pin/I²C), VBUSDET interface with 910kΩ external resistor, interrupt-driven status reporting via INTB, and support for Default/1.5A/3A current profile negotiation.
Technical Context
The PI5USB30216AXUAEX implements a dual-path detection architecture: analog CC voltage threshold comparison (VTH1=0.2V, VTH2=0.66V, VTH3=1.23V) for device-mode current mode identification, and programmable I²C-controlled current sourcing (64–356µA) for host-mode profile selection. Its tri-level PORT and ADDR pins configure port role and interface mode without external logic.
It features integrated dead-battery startup behavior-pulling CC1/CC2 low when VDD=0V-and supports audio adapter accessory detection via OUT3. The I²C interface operates at up to 400kHz with slave addresses 0x7A (ADDR=VDD) or 0x76 (ADDR=GND), and uses register-mapped status (0x03 interrupt, 0x04 CC status) with auto-clearing flags on read.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7V–5.5V - Enables direct connection to single-cell Li-ion or 3.3V/5V system rails without LDO. |
| Operating Temperature | –40°C to +85°C - Qualified for industrial-grade mobile and docking station thermal environments. |
| CC Pull-down (Device) | 5.1kΩ ±10% - Matches USB Type-C SNK Rd spec for reliable default-mode attachment detection. |
| CC Pull-up (Host) | 80µA typ. (Default), 180µA (1.5A), 330µA (3A) - Programmable sourcing meets USB BC1.2 and Type-C current mode requirements. |
| VBUS Detection Threshold | 3.0V typ. with 910kΩ external resistor - Enables robust VBUS presence sensing up to 28V input via resistive divider. |
| I²C Interface Speed | Up to 400kHz Fast Mode - Supports real-time status polling and register updates in high-throughput embedded systems. |
| Standby Current (Dual-Role) | 45–65µA - Ultra-low quiescent draw extends battery life in always-on USB-C detection paths. |
Pinout & Package
PI5USB30216AXUAEX is housed in a 12-contact STQFN package measuring 1.6mm × 1.6mm with 0.4mm pitch and wettable flanks - optimized for space-constrained USB-C connector routing on mobile PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CC1 / CC2 | Configuration Channel I/O | Bi-directional analog interface for USB-C cable orientation, role negotiation, and current mode detection per USB Type-C spec. |
| PORT | Tri-level digital input | Determines port role: GND = Device (SNK), floating = Dual-Role (DRP), VDD = Host (SRC); sets default register bits [2:1]. |
| ADDR | Tri-level digital input | Selects control mode: floating = pin control; VDD/GND = I²C enabled with slave address bit 6 = 1/0 (0x7A/0x76). |
| VBUSDET | Analog input | High-voltage tolerant (4–28V) input requiring 910kΩ external resistor to detect VBUS presence in device-mode operation. |
| INTB / OUT3 | Open-drain output | In I²C mode: active-Low interrupt on register change; in pin mode: audio adapter detection (LOW = detected). |
| SDA / OUT1 & SCL / OUT2 | Bi-directional I²C / open-drain outputs | In pin mode: encode host current mode (Default/Medium/High) as 2-bit open-drain signals per Table 1B. |
| ID | Open-drain output | Asserts LOW when device attached in host/dual-role mode; provides hardware interrupt independent of I²C bus. |
| ENB | Active-low enable input | Pulls internal weak pull-up to disable chip: ENB=VDD → all outputs Hi-Z (except CC1/CC2 pulled low), IDD <5µA. |
Key Features
| Feature | Design Value |
|---|---|
| USB Type-C 1.1 Compliance | Fully implements CC line detection, orientation sensing, and role negotiation per specification - no firmware required for basic operation. |
| Dual Control Interface | Hardware-pin mode (PORT/ADDR) enables boot-time configuration without MCU; I²C mode adds runtime flexibility for dynamic port reassignment. |
| Integrated Current Sources & Resistors | Eliminates 6 external components (Rd, Ip, VREF, dividers) - reduces BOM count and layout area vs discrete solutions. |
| Dead-Battery Startup Support | Drives CC1/CC2 low at VDD=0V - ensures host ports recognize unpowered devices and initiate charging before system power-up. |
| Audio Adapter Detection | Dedicated OUT3 pin reports audio accessory attachment directly - enables OS-level audio routing without I²C polling or GPIO expansion. |
Applications
| Mobile Phone Charging Port | Notebook Docking Interface |
|---|---|
|
Use Scenario: Detecting USB-C cable insertion, orientation, and host charging capability in smartphone charging circuits. IC Role / Device Role / Timing Role: Plug-in detector and current mode negotiator - performs real-time CC voltage sampling and reports SNK Rd state or SRC Ip level to PMIC. Use Value: Enables automatic switch between data transfer and fast-charging modes using only two CC pins - eliminates need for separate orientation sensors or charge controller handshaking. |
Use Scenario: Managing multi-role USB-C connectivity on laptop docking stations supporting host/peripheral/alt-mode switching. IC Role / Device Role / Timing Role: Dual-role port manager - toggles CC1/CC2 every 60ms until role lock, then asserts ID/INTB to notify host CPU of attachment event. Use Value: Reduces system wake latency by 12ms vs software-based polling - interrupt-driven detection ensures immediate response to hot-plug events. |
| Tablet Peripheral Hub | USB-C Audio Adapter Interface |
|

FAQ
What is the function of the ENB pin?
The ENB pin is an active-low enable input with internal ~5MΩ pull-up. When pulled high (ENB=VDD), the device enters ultra-low-power disable state: all outputs go Hi-Z except CC1/CC2, which are pulled low with 5.1kΩ resistors; I²C interface resets; total current drops below 5µA. Pulling ENB low activates full functionality.
How does the PI5USB30216AXUAEX detect audio adapter accessories?
It monitors CC1/CC2 voltage patterns unique to USB-C audio adapters (e.g., specific Ra/Rd resistor combinations). When detected, it drives the OUT3 pin LOW within 150µs - providing a hardware-level signal to the baseband processor without requiring I²C register reads or firmware interpretation.
Can the PI5USB30216AXUAEX operate without an I²C master?
Yes - in pin-control mode (ADDR floating), it uses PORT, ID, OUT1, OUT2, and OUT3 for role selection and status reporting. No I²C master is needed for basic USB-C detection, orientation, and current mode indication - making it ideal for resource-constrained microcontrollers or FPGA-based designs.
What external components are required for VBUS detection?
A single 910kΩ ±5% resistor must connect the system VBUS rail to the VBUSDET pin. This forms a voltage divider that scales VBUS (up to 28V) to a safe level for the internal comparator - no additional capacitors, regulators, or protection diodes are required.
