RS2588BYF5

Overview

The RS2588BYF5 is a power switch IC manufactured by Runic Technology, designed for high-side load distribution. It features a P-channel output capable of delivering a maximum continuous current of 2.6A. The device operates within a load voltage range of 2.5V to 5.5V and utilizes a SOT-23-5 surface-mount package. Key electrical specifications include a typical on-resistance of 70 milliohms and an open/switch interface type. The component supports non-inverted input logic and provides comprehensive fault protection mechanisms.

Feature Summary

• Integrates fixed current limiting, over-temperature shutdown, reverse battery protection, short-circuit protection, and UVLO for robust system reliability.
• Provides status flag indication and controlled load release functionality for enhanced monitoring and safe power management.
• Features a single-channel high-side P-channel configuration with a 1:1 input-to-output ratio for direct control applications.

Applications

• High-side power switching in portable electronic devices
• Load distribution in automotive infotainment systems
• Power management units for industrial control equipment

Procurement Notes

Verify the specific suffix 'BYF5' against the manufacturer's official datasheet to confirm pinout compatibility and functional parameters. Ensure the selected variant matches the required thermal performance and packaging style for the target PCB layout. Cross-reference the RoHS3 compliance status and MSL rating during the sourcing phase to guarantee adherence to environmental regulations and assembly process requirements.

Selection Notes

Select this component when a high-side switch with integrated protection is required for loads up to 2.6A. The low on-resistance minimizes power dissipation, while the built-in fault protections reduce external component count. Consider the operating temperature range and package dimensions for integration into space-constrained designs requiring reliable power sequencing and monitoring capabilities.

Part Context

This part belongs to the Runic Technology power switch family, focusing on efficient power distribution solutions. The RS2588 series offers various configurations tailored for different current and voltage requirements. The BYF5 suffix denotes a specific package and tape-and-reel configuration suitable for automated surface-mount assembly processes in mass production environments.

Replacement Considerations

Consult the official datasheet for cross-reference information regarding compatible substitute parts. Verify that alternative components match the 2.6A current rating, 70mΩ on-resistance, and SOT-23-5 footprint to ensure seamless integration without redesigning the printed circuit board or altering the protection scheme.
