Overview
The R5540K001B-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 maximum current limit of 350 mA. The device features a typical on-resistance of 180 mΩ and is housed in a DFN-PLP-1010-4F-4 package. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a low on-resistance N-channel MOSFET for efficient power distribution
- Provides overcurrent protection with a defined current limit threshold
- Operates with a wide input voltage range starting from 750 mV
Applications
- Portable electronic devices requiring efficient power management
- Battery-powered systems needing load switching capabilities
- Consumer electronics utilizing USB or similar peripheral interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specific ordering code R5540K001B-TR and package type DFN-PLP-1010-4F-4. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet to maintain reliability before soldering.
Selection Notes
Select this component when a compact, low-voltage load switch is required for single-channel applications. The 750 mV minimum operating voltage makes it suitable for battery-backed systems. Compare against other R5540K variants if different current ratings or package sizes are needed for the specific design constraints.
Part Context
This part belongs to the R5540K series of load switches designed for portable applications. It complements other power management solutions like the RP401K boost converter and RP506K buck converter from the same manufacturer, offering integrated control for complete power system architectures in mobile devices.
Replacement Considerations
Direct substitutes include other variants within the R5540K series such as R5540K002C-TR, provided pin compatibility and electrical specifications align with the original design requirements.
