RT2528GSP

Overview

The RT2528GSP is a high-side power distribution switch manufactured by Richtek USA Inc., designed for robust load protection in electronic systems. It features an integrated P-channel MOSFET capable of handling a continuous output current of 2.5A with a typical on-resistance of 74 milliohms. The device operates within a load voltage range of 2.5V to 5.5V and utilizes an open/switch interface for control. Key protective functions include adjustable current limiting, over-temperature shutdown, and under-voltage lockout (UVLO). It is housed in an 8-SOP-EP package and holds AEC-Q100 automotive qualification.

Feature Summary

• Integrates adjustable current limiting and thermal protection for comprehensive load safeguarding
• Features an open/switch interface for straightforward digital control logic
• Includes status flag output for real-time fault monitoring and system diagnostics

Applications

• Automotive body electronics load distribution
• High-side switching for peripheral devices in vehicle networks
• Power distribution units requiring adjustable current limits

Procurement Notes

Verify the specific suffix GSP corresponds to the 8-SOP-EP package configuration when sourcing. Confirm that the adjustable current limit setting aligns with your circuit requirements, as this parameter is external to the IC. Ensure compatibility with the 2.5V to 5.5V operating voltage range for your specific application loads. Check for AEC-Q100 certification if deploying in automotive environments.

Selection Notes

Select the RT2528GSP when a high-side switch with adjustable current limiting is required rather than fixed thresholds. Consider the 74 milliohm on-resistance for efficiency calculations against alternative P-channel switches. Evaluate the need for the status flag feature for diagnostic purposes. Compare the 8-SOP-EP footprint against available PCB space constraints relative to other Richtek power switches.

Part Context

This component belongs to Richtek's power distribution IC family, specifically engineered for reliable load management. It complements other PMIC solutions by providing discrete high-side switching capabilities with integrated protection mechanisms. The product line targets applications demanding robust fault handling and precise current control without complex external circuitry.

Replacement Considerations
