PI5PD2557ZCEX

Overview

The PI5PD2557ZCEX is a precision power distribution load switch manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.5 V to 5.5 V and features a maximum on-resistance of 35 mOhms. The device supports an output current of 5 A with adjustable current limiting between 500 mA and 5 A. It includes programmable soft-start capabilities, characterized by a maximum turn-on time of 5 ms and a maximum turn-off time of 2 ms. Designed for surface-mount installation, it is housed in a V-DFN3030-8 package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates precision current limiting with adjustable thresholds to protect downstream loads from overcurrent conditions.
• Features programmable soft-start control to manage inrush current during power-up sequences.
• Provides low on-resistance conduction path to minimize power loss and thermal generation in high-current applications.

Applications

• Power distribution networks in portable computing devices
• Load switching in industrial equipment requiring precise current management
• Peripheral power control in automotive infotainment systems

Procurement Notes
