Product details
Overview
PI3USB9201ZTAEX from Diodes Incorporated is a dual-role USB Battery Charging Specification v1.2 (BC1.2) detector IC supporting both host-mode SDP/CDP/DCP advertisement and client-mode charging-type detection, with integrated bidirectional USB data switches, 1MHz I²C interface, and <1µA shutdown current. It operates from 2.7V to 5.5V across –40°C to +85°C in a 12-pin 2×2mm UQFN package, deployed in USB-C mobile device port controllers for intelligent charge negotiation.
For engineers reviewing the PI3USB9201ZTAEX datasheet, PI3USB9201ZTAEX pinout, PI3USB9201ZTAEX application, or PI3USB9201ZTAEX equivalent, key selection criteria include BC1.2 mode flexibility (host/client), integrated D+/D– switching capability, I²C address configurability (4 options), industrial temperature range, and RoHS 3 / "Green" compliance with halogen/antimony limits.
Technical Context
The PI3USB9201 implements dual-role BC1.2 detection logic with programmable mode selection via I²C: in host mode, it asserts voltage signatures on D+ and D– to identify as SDP, CDP, or DCP; in client mode, it measures D+/D– voltage ratios and timing to classify attached hosts. Detection results are reported back over I²C with status registers.
It integrates two differential, bidirectional USB 2.0 switches (D+ and D– paths) with 2GHz bandwidth and low on-capacitance (<10pF), enabling transparent pass-through for USB enumeration and HID wake-up (e.g., mouse/keyboard). Control is fully synchronized with detection state, and ADDR pins allow up to four unique I²C slave addresses (0x48–0x4B).

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB BC1.2 detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2549RTER | Single-role (host-only) BC1.2 detector with integrated USB switch; no client-mode detection | Limited to host-side applications (e.g., power banks); cannot replace dual-role use cases | Select only if system never operates as USB device and requires higher current handling (up to 3A) |
| NCP380LSN2T2G | Standalone USB load switch (no BC1.2 logic); requires external microcontroller for detection | Increases firmware complexity and component count; lacks integrated detection engine | Choose only when BC1.2 detection is handled elsewhere and only low-RON switching is needed |
Compared with TPS2549RTER and NCP380LSN2T2G, the PI3USB9201ZTAEX uniquely delivers true dual-role BC1.2 detection plus integrated switching in one chip - reducing system-level design effort, eliminating external detection firmware, and enabling compact USB-C port solutions where role reversal is required.

FAQ
What USB charging standards does the PI3USB9201ZTAEX support?
The PI3USB9201ZTAEX supports full USB Battery Charging Specification v1.2, including SDP (Standard Downstream Port), CDP (Charging Downstream Port), and DCP (Dedicated Charging Port) detection and advertisement modes, plus proprietary 1A/2A/2.4A charging profiles used by legacy wall adapters and automotive chargers.
Can the PI3USB9201ZTAEX operate in both host and client modes simultaneously?
No - the PI3USB9201ZTAEX operates in either host mode (advertising charging capability) or client mode (detecting attached charger type), selected at runtime via I²C command. Mode switching is supported but not concurrent; the device uses a single set of D+/D– pins for both roles.
Does the PI3USB9201ZTAEX require external passive components for BC1.2 detection?
No - all BC1.2 detection circuitry, including D+/D– voltage dividers, comparators, and timing logic, is fully integrated. Only standard I²C pull-up resistors (typically 2.2kΩ) and optional VDD decoupling capacitor (1µF) are required for basic operation.
Is the PI3USB9201ZTAEX compatible with USB-C receptacles that route D+ and D– to both top and bottom connector sides?
Yes - the PI3USB9201ZTAEX is explicitly designed for USB-C applications where D+/D– signals are commoned between top and bottom pins. Its integrated bidirectional switches and detection logic handle this topology without external multiplexing or routing complexity.
