SP2526A-2EN-L

Overview

The SP2526A-2EN-L is a dual-channel high-side power switch designed for USB power distribution applications. It features an active-low enable input and supports an input voltage range of 3V to 5.5V. Each channel provides a continuous output current of 500mA with a maximum on-resistance of 150mΩ. The device includes integrated fault protection mechanisms, such as current limiting and thermal shutdown, alongside dual fault flags for status monitoring. It operates within a temperature range of -40°C to +85°C and is available in an NSOIC-8 package.

Feature Summary

• Dual-channel high-side switching architecture with independent control per port
• Integrated fault management including over-current protection and thermal shutdown
• Active-low enable logic for simplified system integration
• Dedicated fault flag outputs for real-time status indication

Applications

• USB hub power distribution circuits
• Portable electronic device power management
• Peripheral port protection systems
• Industrial equipment I/O power switching

Procurement Notes

Verify the specific suffix configuration against official MaxLinear documentation to ensure compatibility with required enable logic and packaging formats. Confirm that the active-low enable requirement aligns with the host controller's output drive capabilities. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when dual-port USB power switching with high-side control is required. Ensure the system design accommodates the 150mΩ on-resistance for acceptable voltage drop at 500mA loads. Verify that the active-low enable signal polarity matches the controlling microcontroller or power management IC outputs. Consider the thermal performance requirements given the SOIC-8 package constraints.
