Overview
The R5524N001A-TR-FE is a single-channel high-side power switch IC designed for USB power distribution applications. Manufactured by Nisshinbo Micro Devices, it operates within a supply voltage range of 2.2 V to 5.5 V. The device supports an output current of 500 mA with a maximum current limit of 650 mA. It features a maximum on-resistance of 150 mOhms and dissipates up to 660 mW of power. The component functions reliably across an operating temperature range from -40°C to +85°C and is housed in an SOT-23-5 surface-mount package.
Feature Summary
- Integrated high-side switching capability optimized for USB port power management
- Built-in overcurrent protection limiting output to 650 mA to safeguard connected loads
- Low on-resistance design minimizes power loss and thermal generation during operation
Applications
- USB hub power distribution circuits
- Portable electronic device power management
- Peripheral interface power switching
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics match project requirements. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure ESD handling protocols are followed during assembly due to the small form factor package.
Selection Notes
Select this component when a single-channel high-side switch with integrated current limiting is required for low-voltage USB applications. Compare on-resistance and current limits against load requirements to ensure adequate headroom. Consider the SOT-23-5 footprint constraints and thermal dissipation capabilities relative to the PCB layout.
Part Context
This part belongs to the R5524N series of USB power switches from Nisshinbo Micro Devices. The series provides compact solutions for managing power delivery in portable electronics. The R5524N001A variant specifically denotes the fixed configuration within this family, distinguished by its single output channel and defined electrical thresholds.
Replacement Considerations
Consult official substitution lists for verified equivalents. Cross-reference parameters such as on-resistance, current limit, and package type to ensure functional compatibility without redesigning the host circuit.
