PI3USB9281CGEEX

Power Management - Specialized Overview

The PI3USB9281CGEEX is a USB port protection and charger detection IC manufactured by Diodes Incorporated. It operates within a supply voltage range of 3 V to 5.5 V and supports an output voltage up to 5.5 V. The device draws a typical operating supply current of 50 uA. It is housed in a 15-CSP (1.5x2.0) package, also described as 15-XFBGA,WLCSP, suitable for surface mount installation. The component functions across a temperature range of -40°C to +85°C.

Power Management - Specialized Feature Summary

• Provides external detection for any USB device connection
• Tolerates voltages up to 28V for enhanced port protection
• Integrates USB sleep charge functionality

Power Management - Specialized Applications

• Mobile communications devices
• Portable consumer electronics requiring USB port protection
• Battery management systems with USB charging interfaces

Power Management - Specialized Procurement Notes

Verify the specific suffix GEEX corresponds to the 15-CSP (1.5x2.0) WLCSP package configuration. Confirm active status and lead times directly with Diodes Incorporated or authorized distributors, as availability may vary. Ensure compatibility with the target PCB footprint for the 15-terminal termination before ordering.

Power Management - Specialized Selection Notes

Select this component when high voltage tolerance up to 28V is required for USB port protection. It is suitable for applications needing integrated charger detection within a compact 15-CSP footprint. Verify that the 3V to 5.5V operating voltage range aligns with the system power rails and that the -40°C to +85°C temperature rating meets environmental requirements.

Power Management - Specialized Part Context

This part belongs to the PI3USB9281 series from Diodes Incorporated, designed for USB port protection and detection. The series includes variants like PI3USB9281CXWEX in UQFN-20 packages. The CGEEX suffix specifically denotes the 15-CSP packaging option, distinguishing it from other form factors in the same functional family.

Power Management - Specialized Replacement Considerations

PI3USB9281CXWEX offers identical electrical functionality but utilizes a 20-UQFN package instead of the 15-CSP. Cross-referencing requires verifying pinout compatibility and physical footprint differences between the CSP and UQFN packages.
