MAX17121ETG+

Overview

The MAX17121ETG+ is a dual high-voltage scan driver designed for TFT LCD applications. It integrates two independent scan drivers within a single package, supporting operation across an industrial temperature range of -40°C to +85°C. The component utilizes a 24-pin TQFN-EP exposed pad surface-mount package. It functions as a dedicated interface for driving liquid crystal displays in consumer electronics such as televisions and monitors.

Feature Summary

• Integrates two independent high-voltage scan drivers for efficient space utilization
• Supports direct interfacing with TFT LCD panels for display control
• Operates reliably within the standard industrial temperature range

Applications

• TFT LCD panel scanning in television sets
• Display driver circuits for computer monitors
• High-voltage signal generation for active matrix liquid crystal displays

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinued status. Confirm package marking matches the 24-TQFN specification. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Validate that the exposed pad thermal design meets system requirements for heat dissipation during operation.

Selection Notes

Select this component when designing systems requiring dual-channel high-voltage output for TFT LCD gate drivers. Consider the 24-TQFN footprint constraints and thermal pad requirements for PCB layout. Evaluate compatibility with existing display timing controllers and voltage supply rails before integration into the final product architecture.
