Overview
The R5540K004D-TR is a single-channel low-side load switch IC manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range of 800 mV to 3.6 V and delivers an output current of 450 mA with a current limit of 700 mA. The device features a maximum on-resistance of 180 mOhms and supports operation temperatures from -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 on-resistance MOSFET for efficient power distribution
- Includes built-in protection circuits against overcurrent conditions
Applications
- Power distribution in portable electronic devices
- Load switching in battery-powered systems
- Peripheral power management in mobile phones
Procurement Notes
Verify the specific suffix 'D' against the official datasheet to confirm pinout and electrical characteristics match design requirements. Ensure the DFN-PLP-1010-4F-4 package dimensions align with PCB footprint constraints. Confirm RoHS compliance status through manufacturer documentation prior to integration.
Selection Notes
Select this component when a compact, low-voltage load switch is required for single-channel applications. The 450 mA continuous current rating suits moderate load scenarios. Consider the 180 mOhm resistance for thermal management calculations. Verify that the 800 mV minimum operating voltage meets system standby requirements.
Part Context
This part belongs to the R5540K series of load switches from Nisshinbo Micro Devices. The series offers various current ratings and packaging options. The R5540K004D-TR specifically provides 450 mA output capability. It is designed for space-constrained consumer electronics requiring reliable power gating.
Replacement Considerations
The R5540K004C-TR is a documented variant within the same series offering identical electrical specifications including 450 mA output and 180 mOhm resistance. Verify if any minor parameter differences exist between the C and D suffixes in the official datasheet before substitution.
