Overview
The R5527K001D-TR is a load switch IC from Nisshinbo Micro Devices, designed for power distribution applications. It features a single output with a maximum continuous current of 1 A and a typical on-resistance of 65 mOhms. The device operates within a supply voltage range of 1.8 V to 5.5 V and supports soft start functionality to manage inrush current. It is housed in a DFN-PLP-1612-4D-4 package and 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 delivery
- Includes built-in soft start circuitry to control turn-on slew rate
- Provides compact surface-mount packaging for space-constrained designs
Applications
- Battery-powered portable electronic devices
- Load switching in mobile communication modules
- Power distribution in consumer electronics systems
Procurement Notes
Verify the specific suffix 'D' against official datasheets to confirm pinout and functional configuration, as variations exist within the series. Ensure compatibility with standard SMD reflow processes for the DFN-PLP-1612-4D-4 package. Confirm RoHS compliance status through manufacturer documentation prior to integration into final assemblies.
Selection Notes
Select this component when a 1 A load switch with integrated soft start is required for 1.8 V to 5.5 V rails. The 65 mOhms on-resistance balances conduction loss and cost. The DFN-PLP-1612-4D-4 package suits applications needing small footprint. Compare against other suffixes in the R5527K series if different pinouts or protection features are needed.
Part Context
The R5527K series comprises battery power line switch ICs featuring soft start functions. These load switches are engineered for high efficiency and reliability in portable applications. The series offers various configurations to suit different current and voltage requirements, maintaining consistent performance standards across the product family.
Replacement Considerations
Check for direct substitutes such as R5527K001A-TR or R5527K001C-TR, which share similar electrical characteristics but may differ in package or internal configuration. Verify pin-to-pin compatibility before substitution.
