MAX16814AUP/V+

LED Driver IC Overview

The MAX16814AUP/V+ is a four-channel high-brightness LED driver IC designed for automotive and industrial lighting applications. It integrates a DC-DC controller supporting Boost, Buck, and SEPIC topologies with an input voltage range of 4.75 V to 40 V. Each channel delivers up to 150 mA output current at a switching frequency between 200 kHz and 2 MHz. The device features PWM dimming capabilities and open LED protection. It operates within a temperature range of -40°C to +125°C and is housed in a TSSOP-20 package.

LED Driver IC Feature Summary

• Integrates four independent constant-current channels for high-brightness LED control
• Supports flexible power stage configurations including Boost, Buck, and SEPIC topologies
• Provides precise pulse-width modulation (PWM) dimming functionality
• Includes hardware-based open LED protection mechanisms

LED Driver IC Applications

• Automotive exterior lighting systems
• High-power LED illumination modules
• Industrial lighting fixtures
• General-purpose high-voltage LED arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'V+' indicates automotive qualification status against the official datasheet. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the input voltage supply remains within the 4.75 V to 40 V operational limits during all transient conditions. Check for RoHS compliance documentation if required by your manufacturing standards.

LED Driver IC Selection Notes

Select this component when a multi-channel solution is required without external multiplexing. The integrated DC-DC controller reduces external component count compared to discrete solutions. Consider the 150 mA per channel limit for total load calculations. The wide operating temperature range suits harsh environments where standard commercial parts may fail.

LED Driver IC Part Context

This part belongs to the MAX16814A series of integrated LED drivers from Analog Devices/Maxim Integrated. It is distinct from single-channel variants like the MAX16812 or higher-current models such as the MAX16834. The family focuses on simplifying high-brightness LED design through integrated power stages and protection features.

LED Driver IC Replacement Considerations

Direct pin-to-pin replacements are limited due to specific channel counts and current ratings. Evaluate the MAX16814AUP without the V+ suffix for non-automotive use cases if available. Cross-reference with other Maxim 4-channel drivers only if topology and current specifications align exactly.
