Overview
The R5523N001A-TR-FE is a USB high-side switch IC manufactured by Nisshinbo Micro Devices. It features one output channel with a maximum continuous output current of 500 mA and a current limit of 750 mA. The device operates within a supply voltage range of 2.2 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 180 mOhms, a maximum turn-on time of 1.4 ms, and a maximum idle time of 5 us. It supports surface mount installation in an SOT-23-5 package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates overcurrent protection, thermal shutdown, and under-voltage lockout for robust power distribution management.
- Designed specifically for USB high-side switching applications requiring precise current limiting and fast response times.
Applications
- USB port power distribution
- Peripheral device power switching
- Battery-powered equipment load control
Procurement Notes
Verify the manufacturer part number against official Nisshinbo documentation to ensure authenticity. Confirm that the specific suffix matches the required reel or cut tape packaging configuration. Cross-reference RoHS compliance status and lead times directly with authorized distributors prior to ordering.
Selection Notes
Select this component when a single-channel high-side switch with a 500 mA capacity is required. Ensure the application voltage does not exceed the 5.5 V maximum rating. Consider the 180 mOhm on-resistance for power loss calculations and verify that the SOT-23-5 package fits the PCB layout constraints.
Part Context
This device belongs to the R5523N series of power switch ICs designed for power distribution. It serves as a protective element in electronic circuits, isolating loads from the main power source while providing active protection against fault conditions such as short circuits or overheating.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative devices based on pinout, voltage ratings, and current limits before substitution.
