MAX25500ATMA/V+T

LED Driver IC Overview

The MAX25500ATMA/V+T is a modular matrix LED backlight driver designed for local-dimming automotive displays. It integrates four independent channels, each controlling 24 outputs, providing a total of 96 current sinks. The device supports high-voltage operation with integrated switches capable of sinking up to 72mA per channel. It operates within a supply voltage range of 3.3V to 5V and functions across an extended temperature range of -40°C to +125°C. The component is housed in a 48-pin LFCSP package.

LED Driver IC Feature Summary

• Modular architecture supporting 4x24 channel configuration for flexible matrix display control
• Integrated linear current regulation with individual channel current sinking capabilities
• Designed specifically for local-dimming applications in automotive LCD backlights

LED Driver IC Applications

• Local-dimming automotive display backlight systems
• Automotive LCD screen illumination control
• High-channel-count LED matrix drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard 'V+' tray variant. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability may vary by region. Ensure the ordering part number matches the required package style for your manufacturing process.

LED Driver IC Selection Notes

Select this component when designing automotive displays requiring localized dimming zones. It is suitable for applications needing independent control over multiple LED segments without external switching components. Consider the thermal performance of the LFCSP package and the 72mA sink capability per channel when planning heat dissipation strategies for dense matrix layouts.
