NCP1840Q8A6MNG

Overview

The NCP1840Q8A6MNG is an 8-channel programmable LED driver IC manufactured by onsemi. It utilizes a charge pump architecture to support LEDs with higher forward voltages while maintaining low operating battery voltage efficiency. The device features integrated PWM dimming capability and operates via an I2C interface for full channel programmability. It is housed in a compact 20-QFN (4x4 mm) package, designed for applications requiring high energy efficiency and low noise performance in portable lighting systems.

Feature Summary

• Supports up to eight separate LED channels with individual programmability
• Integrates a high-efficiency charge pump for enhanced voltage headroom
• Enables precise control through standard I2C communication interface
• Incorporates built-in PWM dimming functionality for brightness adjustment

Applications

• Portable electronic device backlighting
• Smartphone and tablet display illumination
• Camera flash and ambient light modules

Procurement Notes

Verify the complete part number including suffixes against official onsemi documentation to ensure correct package type and temperature rating. Confirm that the specific variant matches your design requirements for pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring independent control of multiple LED strings from a single low-voltage source. The integrated charge pump eliminates the need for external inductors, reducing board space. Ensure the application environment supports the required I2C bus speeds and that thermal management aligns with the QFN package capabilities.

Part Context

This part belongs to onsemi's NCP1840 family of general-purpose LED drivers. The family is characterized by its ability to drive high-forward-voltage LEDs efficiently. The NCP1840Q8A6MNG specifically denotes the automotive-grade or qualified version within this series, offering reliability suitable for demanding consumer electronics environments.

Replacement Considerations

Check for direct cross-references within the NCP1840 series such as NCP1840Q8A6MNTWG. Verify pin compatibility and electrical specifications before substituting with other manufacturers' 8-channel LED drivers.
