MAX16929AGUI/V+

Overview

The MAX16929AGUI/V+ is an automotive-grade LCD driver and power supply controller designed for TFT-LCD applications. It integrates a boost converter, inverting charge pump, and gamma reference generator within a single package. The device operates with an input voltage range of 3.5V to 18V and supports switching frequencies up to 2MHz. It features AEC-Q100 qualification for automotive reliability. The component is housed in a 28-pin TSSOP-EP package with an exposed pad for thermal management.

Feature Summary

• Integrates boost converter, inverting charge pump, and gamma reference for complete TFT-LCD power generation
• AEC-Q100 qualified for automotive environmental stability and reliability requirements
• Supports high-frequency operation up to 2MHz for reduced external component size
• Includes programmable soft-start and protection features for system robustness

Applications

• Automotive TFT-LCD display power supplies
• In-car infotainment system displays
• Digital instrument cluster backlight drivers
• Rear-view camera monitor power circuits

Procurement Notes

Verify the specific suffix 'V+' indicates lead-free RoHS compliance when sourcing. Confirm availability status as distribution channels may report limited stock or end-of-life conditions. Ensure the 28-TSSOP-EP footprint matches the PCB layout requirements before ordering. Cross-reference the full part number with manufacturer documentation to confirm pinout compatibility.

Selection Notes

Select this component for designs requiring a monolithic solution for negative and positive LCD voltages. Consider the 28-pin TSSOP-EP package for thermal dissipation needs in compact automotive enclosures. Evaluate the 2MHz switching frequency capability against EMI constraints in the vehicle environment. Verify that the input voltage range aligns with the vehicle's battery and alternator specifications.

Part Context

This part belongs to the MAX16929 family of automotive LCD drivers from Analog Devices/Maxim Integrated. It serves as a specialized PMIC for display panels, replacing discrete boost and inverter solutions. The AGUI variant specifies the automotive grade and TSSOP-EP packaging. It complements other Maxim display drivers by offering integrated gamma references and control logic.

Replacement Considerations

Check for direct cross-reference models within the MAX16929 series such as MAX16929DGUI/V+. Verify functional equivalence regarding pinout and electrical parameters before substitution. Consult official replacement guides for any updated revisions or pin-compatible alternatives.
