MAX25220ATJ/V+T

Power Management - Specialized Overview

The MAX25220ATJ/V+T is an automotive-grade, four-channel TFT-LCD power supply featuring an integrated VCOM buffer. It operates from a single supply voltage ranging from 2.65V to 5.5V and communicates via an I2C interface. The device is housed in a 32-pin TQFN-EP package (5x5 mm) and is qualified under AEC-Q100 standards. It supports an operating temperature range of -40°C to +125°C, with a typical supply current of 1.5mA, designed for reliable performance in demanding automotive display applications.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the component meets AEC-Q100 Grade 1 requirements for your specific application environment. Ensure the I2C address configuration matches your system design before integration. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts.

Power Management - Specialized Selection Notes

Select this component when a compact, multi-output solution is required for automotive displays. The integrated VCOM buffer simplifies design by eliminating external components typically needed for common voltage generation. Consider the 32-pin TQFN footprint for space-constrained board designs. Verify that the input voltage range aligns with the vehicle's power bus specifications.

Power Management - Specialized Part Context

This part belongs to Maxim Integrated's family of automotive display power management ICs. It complements other drivers by providing stable, regulated rails specifically tuned for TFT-LCD panels. The series emphasizes high integration and low noise to maintain image quality in critical safety-related visual interfaces within modern vehicles.

Power Management - Specialized Replacement Considerations

Direct substitutes include the MAX25220ATJ/V+ (tray version) if reel packaging is not required. Check for updated revisions such as MAX25220ATJ/VY+ which may offer minor manufacturing improvements while maintaining functional equivalence. Always verify pin-to-pin compatibility before swapping.
