Product details
Overview
PI5USB1468AZAEX from Pericom Semiconductor is a USB host charger controller IC supporting BC1.2, YD/T-1591, Apple 1A, Samsung, Sony Ericsson, and Amazon Kindle Fire fast-charging protocols. It operates from a single 5V ±5% supply, delivers auto-dedicated charging mode with D+/D− signal conditioning for sleep-mode charging, and integrates ±4kV IEC61000-4-2 ESD protection on D+/D− pins. Used in notebook PCs to enable reliable battery charging of smartphones and tablets during S3 sleep state.
For engineers reviewing the PI5USB1468AZAEX datasheet, PI5USB1468AZAEX pinout, PI5USB1468AZAEX application, or PI5USB1468AZAEX equivalent, this page provides verified technical context, validated pin functions, real-world charging protocol support, USB 2.0 signal integrity specs (≤0.6 dB insertion loss, 1350 MHz -3dB BW), and confirmed alternative options for host-side USB charging design.
Technical Context
The PI5USB1468AZAEX implements dual-role USB port management: it actively configures D+/D− voltage levels to emulate DCP/CDP/SDP modes per BC1.2 and OEM-specific protocols, while enabling transparent USB 2.0 data pass-through for mouse/keyboard wake-up in S3. Its SB/ and SEL pins control mode selection via truth-table-defined logic states.
It features integrated load-sensing detection, anti-loop HDD protection, and automatic device classification based on USB signaling characteristics (e.g., data rate, D+/D− resistance ratios). The internal switch path maintains ≤5 Ω RON for HS signals and ≤10 Ω for FS signals, with <10 ps intra-pair skew and -30 dB crosstalk at 240 MHz.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB host charger controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PI5USB1458AZAE | Same package and pinout; lacks INT pin (pin 1 is NC), no interrupt output functionality. | Used where host firmware polling replaces interrupt-driven event handling; lower cost where timing-critical notifications are unnecessary. | Select when interrupt signaling is not required and BOM cost optimization is prioritized over firmware responsiveness. |
| TPS2546RTER | TI part with integrated 5V power switch; supports BC1.2 only (no YD/T-1591 or OEM fast-charge modes); different pinout and control logic. | Targeted at simpler host systems requiring only BC1.2 compliance; no mouse/keyboard pass-through or S3 sleep charging support. | Choose when design scope is limited to BC1.2 DCP/CDP and integrated power switching is preferred over discrete FET control. |
Compared with PI5USB1458AZAE, the PI5USB1468AZAEX adds deterministic interrupt signaling for faster host response; versus TPS2546RTER, it delivers broader OEM protocol coverage and S3-aware USB data pass-through-critical for notebook and docking applications requiring multi-standard compatibility.

FAQ
What charging protocols does PI5USB1468AZAEX support beyond BC1.2?
The PI5USB1468AZAEX supports YD/T-1591 (Chinese telecom standard), Apple 1A fast-charge, Samsung Adaptive Fast Charging, Sony Ericsson proprietary mode, and Amazon Kindle Fire charging-all confirmed in Pericom's official documentation and truth table. It does not support USB PD or QC protocols, as it operates exclusively at the USB 2.0 data-line signaling layer without voltage negotiation.
How does the PI5USB1468AZAEX enable charging during S3 sleep mode?
When the host asserts SB/ low (indicating S3 entry), the PI5USB1468AZAEX reconfigures D+/D− to fixed voltage levels matching BC1.2 DCP requirements (D+ = D− ≈ 0.6 V). This emulates a dedicated charging port, allowing attached devices to draw up to 1.5A without host enumeration-verified by Pericom's application note AN-13-0147 and block diagram analysis.
Is the INT pin on PI5USB1468AZAEX compatible with 3.3V microcontrollers?
Yes-the INT pin is open-drain with 4 mA sink capability and a typical VOL of 0.25 V at IOL = 4 mA. When used with a 3.3V pull-up resistor, it produces a clean logic-low signal recognized by 3.3V I/O domains; no level-shifting is required, as confirmed in the DC Electrical Characteristics table (page 4).
Can PI5USB1468AZAEX coexist with USB 2.0 high-speed data transfer during charging?
No-during Auto Dedicated Charging Mode (DCP), D+/D− are shorted internally to emulate a dedicated port, disabling USB data communication. However, in CDP/SDP modes or mouse/keyboard pass-through mode (activated via SB/ and SEL), full USB 2.0 HS/FS data transfer is preserved with ≤0.6 dB insertion loss and 1350 MHz bandwidth, as measured in Pericom's dynamic characterization (page 5).
