Overview
The R5540K001D-TR is a single-channel N-channel load switch IC from the R5540K series, manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 750 mV to 3.6 V and supports an output current of 200 mA with a current limit of 350 mA. The device features a maximum on-resistance of 180 mOhms and is housed in a DFN-PLP-1010-4F-4 package. It functions as a low-side power distribution switch suitable for portable electronics.
Feature Summary
- Integrates an N-channel MOSFET for efficient low-side power switching
- Provides overcurrent protection via internal current limiting circuitry
- Designed for compact surface-mount applications with minimal footprint
Applications
- Portable electronic devices requiring power distribution management
- Battery-powered equipment needing efficient load switching
- General-purpose power distribution in consumer electronics
Procurement Notes
Verify the specific suffix 'D' against official Nisshinbo documentation to confirm pinout and electrical characteristics, as variations exist within the R5540K family. Ensure compatibility with the target PCB layout for the DFN-PLP-1010-4F-4 package. Cross-reference datasheets for thermal performance requirements under expected load conditions.
Selection Notes
Select this component for applications requiring a low-voltage, single-channel load switch with moderate current capacity. The 180 mOhm on-resistance offers a balance between conduction loss and cost. Verify that the system's ground reference aligns with the low-side configuration and that the control signal levels are compatible with the 750 mV minimum operating voltage.
Part Context
This part belongs to the R5540K series of load switches from Nisshinbo Micro Devices. The series includes variants with different current ratings and configurations. The R5540K001D-TR specifically denotes a 200 mA output variant in tape-and-reel packaging, designed for automated assembly in high-volume production environments.
Replacement Considerations
Check for direct substitutes such as the R5540K001B-TR or R5540K002C-TR, which share similar form factors and electrical profiles within the same series. Confirm functional equivalence regarding current limits and on-resistance before substitution.
