MAX17119ETI+

Overview

The MAX17119ETI+ is a 10-channel scan driver designed for TFT LCD applications, featuring an integrated Global Pixel Modulation (GPM) function. It operates within a supply voltage range of 2.7V to 5.5V and supports a maximum clock frequency of 50 kHz. The device is housed in a 28-pin TQFN package with exposed pad, suitable for surface-mount installation. It functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a dedicated discharge channel for efficient pixel reset operations.
• Includes an on-chip voltage detector to monitor system power integrity.
• Supports Global Pixel Modulation to enhance display contrast and uniformity.

Applications

• TFT LCD panel scanning drivers
• Portable electronic displays
• Industrial control panels

Procurement Notes

Verify the specific suffix ETI+ against the official Analog Devices datasheet to confirm the 28-TQFN package and lead-free compliance. Confirm current availability status as distribution channels may list limited stock or obsolete status. Ensure the design-in process accounts for the recommended operating conditions specified in the electrical characteristics table.

Selection Notes

Select this component when a compact solution for driving small-to-medium TFT LCDs is required. The integrated GPM feature reduces external component count compared to standard scan drivers. Verify that the 50 kHz clock speed meets the refresh rate requirements of the target display panel. Ensure the PCB layout accommodates the thermal pad for adequate heat dissipation.

Part Context

This part belongs to the Maxim Integrated LCD Driver family, specifically optimized for portable devices. It replaces older discrete transistor-based scanning solutions by integrating multiple channels into a single IC. The product line focuses on reducing board space and power consumption for mobile and handheld display applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify if newer revisions have superseded this specific package variant. Cross-reference functional parameters such as channel count and drive current with potential substitutes.
