PI5USB1468AZAEX

Analog Switches - Special Purpose Overview

The PI5USB1468AZAEX is a USB Host Charger Controller IC designed to manage communication for charging battery-powered handheld devices. It supports BC1.2, YD/T-1591, and various non-standard fast charging protocols including Apple 1A and Amazon Kindle Fire. The device operates on a single 5V ±5% power supply within a -40°C to +85°C temperature range. It features an integrated Automatic USB Device Identification Circuit and provides ESD protection up to +/-4kV contact per IEC61000-4-2. Packaged in an 8-contact TDFN (ZA) measuring 2.0mm x 2.0mm x 0.75mm, it includes anti-loop protection for HDDs and distinguishes between High-Speed devices and mice/keyboards.

Analog Switches - Special Purpose Feature Summary

• Supports multiple charging modes including DCP, CDP, SDP, and proprietary fast charging protocols.
• Integrates automatic load sensing and device identification to configure appropriate charging modes.
• Provides mouse and keyboard pass-through functionality to maintain system wake-up capabilities during sleep states.
• Includes anti-loop protection circuitry to prevent continuous cycling of hard disk drives.

Analog Switches - Special Purpose Applications

• Notebook PCs requiring charge-in-sleep functionality
• Desktop computers with USB host ports
• Charging docks and hubs

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Ensure that the selected variant matches the required pin configuration, particularly regarding the INT versus INT/ output options available on different versions of this controller family.

Analog Switches - Special Purpose Selection Notes

Select the PI5USB1468AZAEX when designing systems that require automatic detection of diverse charging standards without manual configuration. Consider the 8-pin TDFN package constraints for space-limited PCB layouts. Evaluate the need for the specific open-drain INT output provided by the 'A' suffix version compared to the open-source alternative.

Analog Switches - Special Purpose Part Context

This component belongs to the PI5USB1468 series of USB charger controllers manufactured by Diodes Incorporated (formerly Pericom). The series addresses the challenge of charging mobile devices from host computers that may be in low-power states. The 'A' designation typically indicates specific internal logic variations, such as the INT output polarity, while maintaining identical core charging management functions.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements must support the same BC1.2 and proprietary protocol suite. Verify compatibility with the 8-pin TDFN (ZA) footprint. Note that other variants in the PI5USB1468 family may differ in the interrupt output type (INT vs INT/) or control logic thresholds.
