RS2588CYF5

Overview

The RS2588CYF5 is a single-channel high-side power switch manufactured by Runic Technology, housed in an SOT-23-5 package. It utilizes a P-channel output configuration with a maximum continuous output current of 2.6A and a typical on-resistance of 70 milliohms. The device operates within a load voltage range of 2.5V to 5.5V and supports a non-inverted open/switch interface. It functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates comprehensive fault protection including fixed current limiting, overtemperature shutdown, reverse battery protection, short circuit protection, and under-voltage lockout.
• Provides status monitoring through a dedicated state flag feature for real-time operational feedback.
• Supports load release functionality to manage power disconnection sequences effectively.

Applications

• High-side switching for peripheral power management in embedded systems
• Load protection circuits requiring reverse battery and short circuit safeguards
• Power distribution units needing integrated thermal and current limiting

Procurement Notes

Verify the complete part number RS2588CYF5 against official Runic Technology datasheets to ensure correct suffix alignment. Confirm that the required packaging format matches available distributor options. Validate RoHS3 compliance requirements against specific project standards before finalizing procurement orders.

Selection Notes

Select this component when a high-side P-channel switch with integrated fault protection is required. Ensure the load voltage stays within the 2.5V to 5.5V range. Verify that the 2.6A current capacity meets system demands. Consider the SOT-23-5 package constraints for PCB layout and thermal dissipation needs.

Part Context

This device belongs to the Runic Technology PMIC portfolio, specifically designed as a power distribution switch. It integrates control logic and protection circuits into a compact surface-mount form factor. The component serves as a critical interface between power sources and sensitive loads in consumer and industrial electronics.

Replacement Considerations

Consult official manufacturer substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully. Do not assume compatibility based solely on package similarity or generic function without validating specific parameter limits.

FAQ

What type of input signal controls the RS2588CYF5?

The device uses a non-inverted open/switch interface, meaning the input signal directly controls the switch state without logical inversion.

Does the RS2588CYF5 include reverse battery protection?

Yes, the component includes built-in reverse battery protection as part of its comprehensive fault protection suite.
