R5523N001B-TR-FE

Overview

The R5523N001B-TR-FE is a USB high-side switch IC manufactured by Nisshinbo Micro Devices. It features one output with a maximum continuous output current of 500 mA and a current limit of 750 mA. The device has a maximum on-resistance of 180 mOhms, operating voltage range from 2.2 V to 5.5 V, and operates within a temperature range of -40°C to +85°C. It includes built-in protection against overcurrent, thermal issues, and undervoltage.

Feature Summary

• Integrated high-side power switching for USB applications
• Built-in overcurrent, thermal, and undervoltage protection
• Low on-resistance for efficient power distribution

Applications

• USB port power management
• Peripheral device power switching
• Portable electronic equipment power distribution

Procurement Notes

Verify the specific suffix TR-FE corresponds to the required reel or cut tape packaging configuration as listed in official distributor catalogs. Confirm RoHS compliance status through the manufacturer's datasheet before finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when a single-channel high-side switch with 500 mA capacity is required. Ensure the load current does not exceed the 750 mA limit. Verify that the system voltage remains within the 2.2 V to 5.5 V operational range and that the SOT-23-5 package fits the design constraints.

Part Context

This part belongs to the R5523N series of USB power switches from Nisshinbo Micro Devices. It is designed for power distribution in portable devices requiring reliable high-side switching with integrated protection features to safeguard connected peripherals and the host system from electrical faults.

Replacement Considerations

Check for direct substitutes within the R5523N series, such as the R5523N001A-TR-FE, which shares similar specifications but may have minor parameter variations. Always verify pin compatibility and electrical characteristics against the original datasheet before substitution.
