MAX25220ATJ/VY+T

Power Management - Specialized Overview

The MAX25220ATJ/VY+T is an automotive-grade, four-channel TFT-LCD power supply featuring an integrated VCOM buffer. Designed for infotainment displays, it operates from a 2.65V to 5.5V supply with a typical supply current of 1.5mA. The device supports output voltages up to 36V and includes negative voltage generation capabilities. It is housed in a 32-pin TQFN-EP package (5mm x 5mm) and is qualified to AEC-Q100 standards for operation across the -40°C to +125°C temperature range.

Power Management - Specialized Procurement Notes

Verify the complete part number including suffixes such as 'T' for tape-and-reel packaging when ordering. Confirm that the specific variant matches the required automotive grade and pinout configuration. Ensure compatibility with existing board layouts regarding the 32-pin TQFN-EP footprint. Cross-reference the manufacturer's latest documentation for any updates to electrical characteristics or recommended operating conditions prior to final procurement.

Power Management - Specialized Selection Notes

Select this component for applications requiring a single-chip solution for multiple LCD rails. It is suitable where space constraints favor a compact 5x5mm package over discrete solutions. Consider its AEC-Q100 qualification for reliability in harsh automotive environments. Evaluate the 36V output capability against specific panel requirements to ensure adequate headroom for boost converters.

Power Management - Specialized Part Context

This device belongs to Maxim Integrated’s portfolio of display power management ICs, now under Analog Devices Inc. It addresses the complexity of powering modern automotive TFT screens by integrating multiple regulators into one unit. The series focuses on reducing bill-of-materials count and simplifying design-in processes for display subsystems in connected vehicles.

Power Management - Specialized Replacement Considerations

Check for direct cross-references within the Analog Devices product line. Verify pin-to-pin compatibility if substituting with other MAX25xxx series variants. Ensure alternative components meet the same AEC-Q100 automotive qualification and thermal performance specifications.
