MAX20069BGTLA/VY+

Overview

The MAX20069BGTLA/VY+ is an automotive-grade integrated circuit designed for high-resolution display systems. It functions as an I2C-controlled backlight driver and TFT-LCD bias power supply. The device integrates four independent LED backlight channels, each capable of delivering up to 150mA. Additionally, it provides four dedicated outputs for generating the positive and negative bias voltages required by TFT-LCD panels. This integration reduces component count and board space in automotive infotainment applications.

Feature Summary

• Integrates four-channel LED backlight driving with individual current control
• Includes four-output DC-DC converter for TFT-LCD panel bias generation
• Features I2C interface for digital control and configuration
• Designed specifically for automotive environmental reliability standards

Applications

• Automotive infotainment system displays
• High-resolution automotive instrument clusters
• Car navigation screen power management
• Rear-seat entertainment system displays

Procurement Notes

Verify the specific suffix VY+ against the official Analog Devices datasheet to confirm package type and tape/reel specifications. Ensure the procurement channel provides valid traceability documentation for automotive-grade components. Confirm that the requested part matches the exact temperature range and functional requirements defined in the product specification before finalizing orders.

Selection Notes

Select this component when designing automotive displays requiring combined backlight and LCD bias power in a single package. It is suitable for applications needing precise I2C-controlled LED current regulation alongside stable TFT voltage rails. Consider its automotive qualification if the environment demands extended temperature performance and high reliability standards compared to consumer-grade alternatives.

Part Context
