Overview
The R5524N004A-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 650 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 150 mOhms, a maximum turn-on time of 400 us, and a maximum idle time of 50 us. It supports a power dissipation of 660 mW and functions across an operating temperature range from -40 C to +85 C.
Feature Summary
- Provides high-side switching capability for USB power distribution applications
- Integrates overcurrent protection with a defined current limit threshold
- Features low on-resistance to minimize power loss during conduction
Applications
- USB port power switching
- Peripheral device power management
- Battery-powered equipment load switching
Procurement Notes
Verify the complete part number including suffixes against official manufacturer documentation to ensure correct package and tape/reel specifications. Confirm RoHS compliance status through the specific datasheet provided by Nisshinbo Micro Devices. Cross-reference ordering information with authorized distributors to validate availability and lead times prior to procurement planning.
Selection Notes
Select this component when a single-channel high-side switch is required for USB interfaces. Ensure the load current does not exceed the 500 mA continuous rating or the 650 mA limit. Verify that the system supply voltage falls within the 2.2 V to 5.5 V operational window. Consider the SOT-23-5 package constraints for thermal management given the 660 mW power dissipation rating.
Part Context
This device belongs to the R5524N series of power switch ICs designed for power distribution. It is categorized under USB power switches and general power switch ICs within the Nisshinbo portfolio. The series targets applications requiring compact solutions for managing power delivery to peripheral loads in portable electronics.
Replacement Considerations
Consult official substitution guides for compatible alternatives within the R5524N family or equivalent high-side switch ICs from other manufacturers. Verify pin compatibility and electrical parameter alignment before considering any substitute part numbers.
