Overview
The R5527K001A-TR is a battery power line switch IC from Nisshinbo Micro Devices, functioning as a load switch with an integrated soft start feature. It supports a single output channel and delivers a maximum continuous output current of 1 A. The device operates within a supply voltage range of 1.8 V to 5.5 V. Key electrical specifications include a maximum on-resistance of 65 mΩ and a maximum turn-on time of 7.5 ms. The component is rated for an operating temperature range from -40°C to +85°C and is housed in a DFN-PLP-1612-4D-4 surface-mount package.
Feature Summary
- Integrates a soft start function to manage inrush current during activation.
- Features low on-resistance MOSFET for efficient power distribution.
- Provides high-side switching capability for battery-powered applications.
Applications
- Battery protection circuits in portable electronic devices
- Load switching for peripheral power rails in mobile systems
- Power management in consumer electronics requiring controlled startup
Procurement Notes
Verify the specific suffix (e.g., 001A) against the official datasheet to ensure correct voltage thresholds and pin configuration. Confirm that the DFN-PLP-1612-4D-4 footprint matches the PCB layout requirements. Check RoHS compliance status directly with the manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-channel high-side switch with controlled ramp-up is required for battery lines. Ensure the input voltage stays within the 1.8 V to 5.5 V operational window. Consider the 65 mΩ on-resistance for thermal management and efficiency calculations in low-power designs.
Part Context
This part belongs to the R5527K series of load switches designed by Nisshinbo Micro Devices. The series focuses on power distribution ICs for portable devices, offering various configurations with different current ratings and package options. The R5527K001A-TR specifically targets applications needing precise control over power delivery timing.
Replacement Considerations
Consult the official Nisshinbo Micro Devices cross-reference list for verified substitutes. Do not assume functional equivalence with other load switches without verifying pinout, voltage ratings, and package dimensions against the original datasheet.
