Overview
The R5540K004C-TR is a low-side power switch IC from Nisshinbo Micro Devices, designed for load distribution applications. It features a single output capable of delivering up to 450 mA continuous current with a maximum on-resistance of 180 mOhms. The device operates within a supply voltage range of 800 mV to 3.6 V and includes a current limit of 700 mA. It functions reliably across an operating temperature range of -40°C to +85°C. Packaged in a DFN-PLP-1010-4F-4 format, it dissipates up to 300 mW.
Feature Summary
- Integrates a low-side N-channel MOSFET for efficient power switching
- Provides inherent current limiting protection against overload conditions
- Optimized for low on-state resistance to minimize power loss
Applications
- Power distribution in portable electronic devices
- Load switching for peripheral modules in mobile systems
- Battery-powered equipment requiring efficient power management
Procurement Notes
Verify the specific suffix C against official datasheets to confirm pinout and electrical characteristics match your design requirements. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging specifications. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.
Selection Notes
Select this component when a low-side switch configuration is required for loads drawing up to 450 mA. The 180 mOhm on-resistance makes it suitable for applications prioritizing efficiency over high-current capacity. Consider the 800 mV minimum operating voltage to ensure compatibility with your system's power rail levels during operation.
Part Context
This part belongs to the R5540K series of load switch ICs from Nisshinbo Micro Devices. The series offers various current ratings and package options tailored for different power distribution needs. The R5540K004C-TR specifically targets mid-range current applications within compact form factors common in modern consumer electronics.
Replacement Considerations
Check the R5540K002C-TR for lower current requirements or the R5540K004D-TR for alternative packaging options. Verify that substitute parts maintain compatible on-resistance and current limit thresholds to ensure circuit performance consistency.
