Overview
The NCR405UX is a linear LED driver IC manufactured by Nexperia, designed for constant current applications. It features a stabilized output current of 50 mA with high accuracy across supply voltage variations. The device utilizes a resistor-equipped PNP transistor architecture with two integrated diodes on a single chip. It supports a maximum input voltage of 40 V and delivers an output voltage up to 38 V. The component operates within a temperature range of -55°C to +150°C and is housed in a compact 6-TSOP (SC-74/SOT-457) surface-mount package.
Feature Summary
- Stabilized output current of 50 mA ensures consistent LED brightness
- High current accuracy maintained despite supply voltage fluctuations
- Low voltage overhead requirement reduces power dissipation
- AEC-Q101 qualified for automotive reliability standards
Applications
- Constant current LED driver circuits
- Generic constant current sources
- Automotive lighting systems
Procurement Notes
Verify the specific suffix 'X' corresponds to the required tape and reel packaging configuration when ordering. Confirm that the AEC-Q101 qualification grade meets the target application's environmental requirements. Ensure the SC-74 footprint matches the PCB design constraints. Check RoHS compliance status against regional regulations before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring precise 50 mA regulation without complex control interfaces. The low overhead voltage makes it suitable for battery-powered or low-voltage supply scenarios. Consider the thermal performance limits given the 750 mW dissipation capability in the small package. Verify external resistor requirements if current adjustment beyond the standard 50 mA setting is necessary.
Part Context
This part belongs to the NCRxxx series of LED drivers from Nexperia, focusing on simplified, robust solutions for automotive and general lighting. The NCR405U variant specifically targets applications needing reliable constant current delivery in space-constrained environments. It complements other Nexperia power management components by providing a dedicated, single-channel solution for LED string driving.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate pin-compatible alternatives only after verifying electrical parameter alignment and thermal characteristics.
