XRP2528IHBTR-1-F

Overview

The XRP2528IHBTR-1-F is a dual-channel high-side power switch manufactured by MaxLinear. It features two independent channels with a maximum output current of 1A per channel and an on-resistance of 150mΩ maximum. The device operates with an input voltage range of 3V to 5.5V and utilizes an active-high enable signal for control. It includes dual fault flags for status monitoring and is housed in a 10-TDFN (3x3) package.

Feature Summary

• Dual-channel architecture providing independent high-side switching capabilities
• Integrated fault flag outputs for real-time status monitoring
• Active-high enable logic for straightforward interface integration

Applications

• USB port power distribution and protection
• Peripheral device power management
• Industrial I/O board load switching

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by MaxLinear. Verification of availability should focus on surplus distributors or alternative replacement parts. Ensure that any sourced units are authentic and match the original specifications, as end-of-life status may affect long-term supply chain stability.

Selection Notes

Select this part when dual isolated high-side switching is required within a 3V to 5.5V system. The 1A per channel rating suits moderate load applications. Consider the 150mΩ on-resistance for thermal management. Verify compatibility with active-high control signals and ensure the 10-TDFN footprint fits the design constraints.

Part Context

Part of the XRP2528 series from MaxLinear, designed for power distribution tasks. It complements single-channel variants like the XRP2527 by offering dual functionality in a compact form factor. The series targets applications requiring reliable load switching with integrated fault detection capabilities.

Replacement Considerations

SP2525A-1EN-L/TR is a documented substitute offering similar high-side switching functions.
