Overview
The R5524K002B-TR is a USB N-channel high-side switch IC from the R5524K series, designed for power distribution applications. It operates within a supply voltage range of 800 mV to 3.6 V and features an SMD/SMT installation style in a DFN-PLP-1820-6 package. The device provides a single output with a maximum on-resistance of 180 mOhms and supports an output current of 450 mA. It includes a current limit function set at 700 mA to protect against overloads. The component functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates N-channel MOSFET for high-side switching control
- Includes built-in current limiting protection circuitry
- Optimized for low on-resistance to minimize power loss
Applications
- USB power distribution circuits
- Portable electronic device power management
- Battery-powered equipment load switching
Procurement Notes
Verify the specific suffix B-TR indicates the reel packaging configuration before ordering. Confirm that the DFN-PLP-1820-6 footprint matches your PCB design constraints. Ensure the operating voltage requirements align with the 800 mV to 3.6 V specification range. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the current limit threshold against your system's overload protection needs.
Selection Notes
Select this component when a compact high-side switch is needed for USB or low-voltage applications. The 180 mOhms on-resistance offers efficiency benefits for moderate current loads up to 450 mA. Consider the DFN-PLP-1820-6 package size for space-constrained designs. The integrated current limit simplifies external protection component requirements. Ensure the input voltage stays within the specified operational window.
