MAX17108ETI+

Overview

The MAX17108ETI+ is a specialized power management integrated circuit designed for thin-film transistor liquid-crystal display applications. It integrates a 10-channel high-voltage level-shifting scan driver and a VCOM amplifier within a single package. The device operates with a supply voltage range of 2.7V to 3.3V and supports bandwidths including 2.5 MHz, 4.2 MHz, 8.7 MHz, 16.4 MHz, 23.4 MHz, and 36 MHz. It features a gain of 96 dB and a noise figure of 10.3 dB, consuming 27 mA of operating current. Packaged in a 5 mm x 5 mm QFN-28 surface-mount format, it functions reliably between -40°C and +85°C.

Feature Summary

• Integrates a 10-channel high-voltage level-shifting scan driver for TFT LCD control
• Includes a dedicated VCOM amplifier optimized for display performance
• Features an operational amplifier with rail-to-rail output and fast slew rate

Applications

• Thin-film transistor liquid-crystal display systems
• LCD television panels
• Computer monitor displays

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details prior to integration. Ensure the specific suffix matches design requirements as ordering variations may exist. Validate that the part status aligns with long-term production plans, as this model may be restricted from new designs.

Selection Notes

Select this component for applications requiring integrated scan driving and VCOM amplification in compact form factors. The QFN-28 package suits space-constrained PCB layouts. Consider the operating temperature range and supply voltage compatibility with existing system rails. Evaluate the integration benefits against discrete solutions to reduce bill of materials complexity.

Part Context

This part belongs to the Maxim Integrated portfolio, now part of Analog Devices Inc. It serves as a specialized PMIC solution for display drivers. The ETI+ suffix indicates a lead-free, halogen-free variant packaged in a tube. It replaces older discrete driver architectures by consolidating multiple functions into a single silicon die.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify functional equivalence of the scan driver channel count and VCOM specifications. Ensure thermal characteristics and package dimensions match the existing footprint.
