Diodes Incorporated PI5USB30216DXUAEX

Overview

PI5USB30216DXUAEX from Diodes Incorporated 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 delivers 80 µA host pull-up current, supports 3A/1.5A/default current modes, operates from 2.7V–5.5V, and functions across –40°C to +85°C in notebooks and docking stations.

For engineers reviewing the PI5USB30216DXUAEX datasheet, PI5USB30216DXUAEX pinout, PI5USB30216DXUAEX application, or PI5USB30216DXUAEX equivalent, key selection criteria include CC detection accuracy, dual-mode control (pin/I²C), VBUSDET interface with 910 kΩ resistor, integrated Rd = 5.1 kΩ pull-down, and interrupt-driven status reporting via INTB.

Technical Context

The PI5USB30216DXUAEX implements a dual-path detection architecture: analog CC voltage threshold comparison (VTH1_SNK = 0.2 V, VTH2_SNK = 0.66 V, VTH3_SNK = 1.23 V) for device-side current mode identification, and programmable current-source sourcing (64–356 µA) for host-side negotiation. Its tri-level PORT and ADDR pins configure port role and control interface without external logic.

I²C communication uses fixed slave addresses (0x7D or 0x3D depending on ADDR level), requires sequential register access, and supports interrupt-driven event handling via INTB with maskable flags in Control Register (0x02). Dead-battery startup forces CC1/CC2 low at VDD = 0 V to enable host-initiated charging.

FAQ

What is the function of the ADDR pin on PI5USB30216DXUAEX?

The ADDR pin selects the control interface mode: floating enables pin-based GPIO control; connection to VDD or GND enables I²C mode with corresponding slave address bits (0x7D or 0x3D). This tri-level configuration eliminates the need for external strapping resistors and allows hardware-revision flexibility without changing firmware.

How does PI5USB30216DXUAEX detect audio adapter accessories?

It identifies audio adapters by measuring the specific resistance signature across CC1/CC2 lines (typically ~1.2 kΩ for analog audio dongles). In pin-control mode, this triggers a low signal on OUT3; in I²C mode, it sets bit 6 of CC Status Register (0x04), allowing the host processor to enable audio codec drivers or mute internal speakers.

Can PI5USB30216DXUAEX operate with a 0 V battery supply?

Yes - its dead-battery startup feature pulls CC1 and CC2 low when VDD = 0 V, enabling an upstream host port to recognize the device as a valid SNK and initiate VBUS-powered charging. This behavior is hardware-automated and requires no firmware initialization or external circuitry.

What is the purpose of the VBUSDET pin and its required external resistor?

VBUSDET monitors system VBUS voltage to determine device attachment in SNK mode. A 910 kΩ ±5% resistor must be placed between the Type-C connector's VBUS and this pin to scale the 4–28 V input down to a safe detection range (2.51–4.01 V threshold), protecting the IC from overvoltage while maintaining accurate attach/detach timing.
