MAX16814BEUP+

LED Driver IC Overview

The MAX16814BEUP+ is a four-channel high-brightness LED driver IC from Analog Devices/Maxim Integrated. It integrates linear current sinks with an internal DC-DC controller supporting boost, buck, and SEPIC topologies. The device operates on a 4.75V to 40V input range and withstands automotive load-dump events. It features adjustable output current up to 150mA per channel, PWM dimming capabilities, and open LED protection. Packaged in a 20-pin TSSOP-EP, it is designed for efficient LED string driving in automotive and general lighting applications.

LED Driver IC Feature Summary

• Integrates four independent linear current sink channels for precise LED control
• Includes an internal current-mode switching DC-DC controller for flexible power conversion
• Supports wide input voltage ranges suitable for direct automotive battery connections
• Provides hardware-based open LED fault detection and protection mechanisms

LED Driver IC Applications

• Automotive interior and exterior lighting systems
• High-brightness LED backlighting for LCD displays
• General solid-state lighting fixtures
• LED modules requiring multi-string current regulation

LED Driver IC Procurement Notes

Verify the specific suffix BEUP against official datasheets to confirm package type and temperature grade. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compatibility with existing PCB footprints for the 20-TSSOP-EP package before procurement. Cross-reference ordering information with Analog Devices official documentation to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when designing circuits requiring integrated DC-DC control alongside linear LED sinking. It is suitable for applications needing robust automotive-grade performance without external controller complexity. Consider the thermal dissipation requirements of the linear sinks relative to the total LED current. Evaluate the need for PWM dimming resolution and frequency settings during the design phase.

LED Driver IC Part Context

This part belongs to the MAX16814 family of integrated LED drivers. It combines high-efficiency power conversion with precise current regulation. The series is engineered for automotive reliability, handling harsh electrical environments. It serves as a compact solution for replacing discrete LED driver architectures.

LED Driver IC Replacement Considerations

Check for MAX16814AUP+ or MAX16814CATP+ variants if different temperature ratings or packages are required. Verify pinout compatibility before substituting with other Maxim LED driver models. Consult official replacement guides for any updated versions within the same product line.
