Overview
The PI5USB2546ZHDEX is a USB charging port controller and load detection power switch manufactured by Diodes Incorporated. It integrates a high-side N-channel power switch rated for 2.5A with advanced load detection capabilities. The device operates within a supply voltage range of 3.0V to 5.5V and features an operating supply current of 270µA. It is housed in a compact 16-UQFN (3x3) package, designed for efficient space-constrained applications requiring precise power management and load identification.
Feature Summary
- Integrates a 2.5A high-side N-channel power switch for robust current handling
- Includes built-in load detection circuitry for automatic charging port identification
- Operates with low standby current to optimize battery life in portable devices
Applications
- Smartphone and tablet charging ports
- Portable electronic device power management
- USB peripheral load detection systems
Procurement Notes
Verify the specific suffix ZHDEX against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with Diodes Incorporated or authorized distributors prior to ordering. Ensure design compatibility with the 16-UQFN footprint and thermal requirements specified in the official documentation.
Selection Notes
Select this component when application requires integrated load detection alongside high-current switching in a minimal footprint. Compare against standard power switches if load identification logic is unnecessary. Verify that the 2.5A continuous current rating meets peak load demands without exceeding thermal limits in the target enclosure.
Part Context
This part belongs to Diodes Incorporated's portfolio of USB interface and power management solutions. It complements other USB switch ICs like the PI5USB2546AZHEX but adds specific load detection functionality. The product line targets mobile and consumer electronics markets requiring reliable power delivery and intelligent port management.
Replacement Considerations
Check for direct pin-compatible alternatives within the PI5USB series. Verify if the PI5USB2546AZHEX meets functional needs if load detection is not required. Consult Diodes Incorporated for updated replacement recommendations as product lifecycles change.
