PI5PD2556ZCEX

Overview

The PI5PD2556ZCEX is a single-channel USB power switch IC manufactured by Diodes Incorporated. It features an N-channel output capable of handling up to 5A of continuous current with a typical on-resistance of 22 milliohms. The device operates within a load voltage range of 2.5V to 5.5V and utilizes an 8-TDFN (3x3) surface-mount package. Integrated protection mechanisms include adjustable current limiting, over-temperature shutdown, and under-voltage lockout. A status flag output provides fault indication, while the interface accepts a non-inverted control signal.

Feature Summary

• Integrates adjustable current limiting and thermal protection for robust circuit safeguarding
• Provides a dedicated status flag output to indicate operational faults or conditions
• Utilizes a compact 8-TDFN package designed for space-constrained surface-mount applications

Applications

• USB port power switching and distribution
• Load driver circuits in portable consumer electronics
• Power management systems requiring high-side switching
