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 pinout and core functionality; lacks INT/ pin variant - uses INT (open-drain) instead of INT/ (open-source) | Requires external pull-up on INT; not compatible with systems expecting active-high interrupt assertion | Select when host GPIO supports open-drain input with pull-up; lower cost where interrupt polarity is flexible |
| TPS2546RTER | TI part with integrated 5-V power switch; higher max current (2.4 A); no Y+/Y− pass-through pins | Cannot support S3 mouse/keyboard wake; designed for standalone charging port, not host-embedded applications | Select when adding VBUS switching and higher current is needed, and S3 pass-through is unnecessary |
Compared with PI5USB1458AZAE, PI5USB1468AZAE+CWX offers identical protocol support but adds flexibility via dual INT/ pin option; versus TPS2546RTER, it trades off integrated power switching for essential S3 wake-through capability required in host-embedded designs.

FAQ
What charging protocols does PI5USB1468AZAE+CWX support?
PI5USB1468AZAE+CWX supports BC1.2 DCP/CDP/SDP, YD/T-1591, Apple 1A/2A, Samsung fast charging, Sony Ericsson fast charging, and Amazon Kindle Fire protocols. It uses automatic device identification to select the correct D+/D− configuration without firmware intervention.
How does the device handle USB sleep mode (S3) while maintaining charging and wake capability?
When SB/ transitions low, PI5USB1468AZAE+CWX enters S3 mode and either enables DCP charging (for non-HID devices) or passes through D+/D− signals (for mouse/keyboard), allowing wake-on-activity. This dual-path behavior is hardware-automated and requires no host CPU involvement.
Is external ESD protection required on D+/D− lines?
No. PI5USB1468AZAE+CWX integrates ±4 kV contact ESD protection on pins 2 (D−) and 3 (D+) per IEC61000-4-2, meeting typical system-level ESD requirements without additional TVS diodes - verified in Diodes' characterization reports.
What is the function of the Y+ and Y− pins?
Y+ and Y− connect to the host USB transceiver's D+ and D− lines. During S3, they enable transparent signal pass-through for low/full-speed HID devices; during S0, they route host-controlled signaling for CDP/SDP enumeration - critical for maintaining wake capability without sacrificing charging.
