Product details
Overview
PI5USB30216CXUAEX from Diodes Incorporated is a USB Type-C™ plug-in detector IC supporting host/device/dual-role port configuration via CC1/CC2 channel sensing, with integrated 5.1 kΩ pull-down resistors (SNK), 80 µA pull-up current source (SRC), I²C and pin-control interfaces, and VBUS detection capability for connector attachment monitoring in portable electronics.
For engineers reviewing the PI5USB30216CXUAEX datasheet, PI5USB30216CXUAEX pinout, PI5USB30216CXUAEX application, or PI5USB30216CXUAEX equivalent, key selection considerations include CC pin voltage threshold accuracy (±0.05 V), dual-mode control flexibility (ADDR-configurable I²C vs. GPIO), industrial temperature operation (−40°C to +85°C), and support for USB Type-C 1.1-compliant orientation auto-detection and 3A charging profile negotiation.
Technical Context
The PI5USB30216CXUAEX implements a dual-path detection architecture: analog CC1/CC2 comparators with programmable thresholds (0.20 V default, 0.66 V medium, 1.23 V high) feed status logic that drives open-drain outputs (ID, OUT1–OUT3) and updates I²C registers (0x03 interrupt, 0x04 CC status). Its internal state machine supports four connection states-unattached, Attached.SNK, Attached.SRC, AudioAccessory-and resets on ENB toggling or VDD drop below 1.0 V.
It integrates tri-level input decoding (PORT, ADDR), 910 kΩ VBUSDET scaling network interface, dead-battery startup (CC1/CC2 pulled low at VDD = 0 V), and I²C slave addressing with two fixed addresses (0x7D/0x75) determined by ADDR pin level. Power management includes active-low ENB with 5 MΩ internal pull-up and <5 µA disable-state current draw.
Key Specifications

| Operating Temp | −40°C to +85°C; qualified for industrial-grade embedded systems including docking stations and tablets |
| I²C Interface | Fast-mode (400 kHz); no offset byte; sequential register access required; ADDR pin selects slave address (0x75 or 0x7D) |
Pinout & Package
PI5USB30216CXUAEX is housed in a 12-contact STQFN package measuring 1.6 mm × 1.6 mm with 0.4 mm pitch and wettable flank terminals for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | CC1, CC2 | Bi-directional configuration channel I/O; internally clamped to VDD+0.5 V; used for orientation detection, role negotiation, and accessory identification |
| 3 | PORT | Tri-level input controlling port mode: GND = SNK, float = DRP (Try.SNK), VDD = SRC; sets initial role before I²C override |
| 4 | VBUSDET | Analog input scaled by external 910 kΩ resistor; triggers VBUS presence detection at ~3.0 V threshold for device-attachment inference |
| 5 | ADDR | Tri-level input selecting control mode: float = pin control, VDD/GND = I²C enabled with slave address bit-6 = 1/0 |
| 6 | INTB / OUT3 | Open-drain interrupt output (I²C mode) or audio adapter accessory indicator (pin mode); active-low, 1.6 mA sink capability |
| 7, 8 | SDA / OUT1, SCL / OUT2 | I²C data/clock bidirectional pins; double-function as current-mode detect outputs (OUT1/OUT2) in pin-control device mode |
| 9 | ID | Open-drain host-attachment indicator; pulled low only when acting as SRC and detecting SNK; hi-Z otherwise |
| 10 | GND | System ground reference; shared return path for all analog and digital functions |
| 11 | ENB | Active-low enable with 5 MΩ internal pull-up; forces CC1/CC2 low and disables outputs (except CC/SDA/SCL/INTB) in disabled state |
| 12 | VDD | Primary power supply input; powers internal regulators, comparators, and logic; supports dead-battery startup down to 0 V |
Key Features
| Feature | Design Value |
|---|---|
| Auto-orientation detection | Real-time CC1/CC2 voltage comparison enables automatic USB-C plug insertion direction recognition without MCU polling |
| Dual-control interface | Selectable between hardware pin control (PORT/ADDR) and software-configurable I²C (0x02 control register) for flexible system integration |
| 3A charging profile support | Configurable SRC current modes (80/180/330 µA) and SNK detection thresholds ensure compliance with USB PD 3.0 default/medium/high power contracts |
| Audio accessory detection | OUT3 pin asserts low upon audio adapter attachment (per USB-C spec Appendix A); eliminates need for separate accessory ID circuitry |
| Dead-battery compatibility | CC1/CC2 forced low at VDD = 0 V allows host ports to recognize unpowered devices and initiate VBUS charging automatically |
Applications
| Mobile Phone Charging Port | Notebook Docking Interface |
|---|---|
|
Use Scenario: Detects USB-C cable insertion direction and negotiates host/device role during fast-charging handshakes.

Use Value: Enables native 3A charging without external level shifters or discrete comparators; reduces BOM count by integrating Rd and Ip sources. |
Use Scenario: Manages multi-role connectivity between laptop and peripheral hub with simultaneous video, data, and power delivery. IC Role / Device Role / Timing Role: Dual-role port manager; uses PORT pin to initialize as DRP and switches to SRC/SNK based on CC line biasing; supports Try.SNK for reliable peripheral enumeration. Use Value: Eliminates firmware dependency for basic orientation detection; provides deterministic timing for VBUS assertion and ID assertion within 20 ms of stable CC detection. |
| Tablet Peripheral Adapter | USB-C Audio Dongle |
|
Use Scenario: Enables tablet-to-keyboard/mouse/hub connectivity with automatic role switching and VBUS-powered peripheral support. IC Role / Device Role / Timing Role: Host-mode initiator; detects device attachment via ID pin low pulse and configures charging profile using OUT1/OUT2 logic levels. Use Value: Supports 1.5A charging while maintaining USB 2.0 data path integrity; avoids false triggers from ESD transients due to internal 2000 V HBM protection. |
Use Scenario: Identifies USB-C analog audio adapters (e.g., 3.5 mm jack dongles) and signals host OS to route audio through legacy codec path. IC Role / Device Role / Timing Role: Accessory classifier; asserts OUT3 low only when CC1/CC2 match USB-C Audio Adapter spec (Ra = 1.1 kΩ); ignores debug accessories. Use Value: Provides hardware-level audio accessory detection independent of USB enumeration; reduces OS driver complexity and boot-time latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C plug-in detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB320LAIRTER | Single-supply 3.3 V only; no VDD=2.7–5.5 V range; lacks integrated 3A current mode detection logic | Requires external current-sense resistors and comparator for 3A mode; limited to host-only or device-only configurations | Choose for cost-sensitive, fixed-role designs where I²C control and wide VDD range are not required |
| USB3503A-AEZG | Integrated USB 2.0 switch + Type-C detection; larger QFN-24 package; higher IDD (120 µA active) | Supports simultaneous USB data switching and CC detection; adds signal integrity overhead for pure detection use cases | Choose when combining detection with USB 2.0 path switching; avoid if minimal footprint and ultra-low standby current (<35 µA) are critical |
Compared with TUSB320LAIRTER and USB3503A-AEZG, the PI5USB30216CXUAEX delivers broader supply flexibility, native 3A charging profile support without external components, and smallest footprint (1.6 mm × 1.6 mm), making it optimal for space-constrained mobile and docking applications requiring dual-mode control.

FAQ
What is the function of the ADDR pin on PI5USB30216CXUAEX?
The ADDR pin is a tri-level input that selects the control interface mode: floating enables pin control (PORT/ENB/OUTx), VDD sets I²C address bit-6 = 1 (0x7D), and GND sets bit-6 = 0 (0x75). It does not affect analog functionality-CC detection and VBUS monitoring remain active regardless of ADDR state.
How does PI5USB30216CXUAEX handle dead-battery conditions?
When VDD = 0 V, internal circuitry pulls CC1 and CC2 low via integrated 5.1 kΩ resistors, signaling to an attached host port that the device is in SNK mode and requesting VBUS power. This enables charging initiation even with zero battery voltage, per USB Type-C dead-battery specification.
Can PI5USB30216CXUAEX detect audio adapters without I²C communication?
Yes-audio adapter detection is implemented in hardware and reported directly on the OUT3 pin: low indicates detection, hi-Z indicates absence. This occurs in both pin-control and I²C modes and requires no register reads, enabling immediate OS-level audio routing decisions.
What is the maximum VBUS voltage the PI5USB30216CXUAEX can safely monitor?
The VBUSDET pin accepts up to 28 V system VBUS, protected by an internal clamp diode limiting voltage to ~5.5 V. A 910 kΩ ±5% resistor must be placed between system VBUS and VBUSDET to scale input and ensure accurate 3.01 V detection threshold across temperature and process variation.
