Overview
The R5524N002B-TR-FE is a single-channel high-side power switch IC designed for USB load distribution. It supports an input voltage range of 1.8 V to 5.5 V and delivers a continuous output current of 500 mA with a peak limit of 650 mA. The device features a maximum on-resistance of 150 mΩ, ensuring low conduction losses. Key timing parameters include a maximum turn-on time of 400 µs and a maximum turn-off time of 50 µs. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Integrated high-side switching capability for precise load control
- Built-in current limiting protection to safeguard connected peripherals
- Low on-resistance design for efficient power distribution
- Compact SOT-23-5 footprint suitable for space-constrained applications
Applications
- USB port power management and distribution
- Peripheral device load switching
- Battery-powered equipment power control
Procurement Notes
Verify the complete part number including the suffix TR-FE to confirm reel packaging specifications. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Cross-reference thermal requirements against the system's ambient operating conditions to maintain performance within the specified -40°C to +85°C range.
Selection Notes
Select this component when a single-channel high-side switch with moderate current capacity is required. The 500 mA rating suits standard USB loads. Consider the 150 mΩ on-resistance for efficiency calculations. Verify that the 5.5 V maximum voltage aligns with the system supply rails. The SOT-23-5 package dictates board layout constraints.
Part Context
This device belongs to the R5524N series of USB high-side switches from Nisshinbo Micro Devices. The series provides integrated protection and control for power distribution networks. The specific model variant defines the electrical characteristics and packaging configuration within this product line.
Replacement Considerations
Check datasheets for alternative single-channel high-side switches with similar 500 mA ratings and SOT-23-5 packages. Verify pinout compatibility and on-resistance values before substitution.
