MAX20428ATIE/VY+

Overview

The MAX20428ATIE/VY+ is an ASIL-C compliant power management IC designed for automotive applications. It integrates seven output channels: three synchronous step-down (buck) converters, one step-up (boost) converter, and three low-dropout (LDO) regulators. The device operates with an input voltage range of 2.7V to 5.5V. It supports a minimum operating temperature of -40°C and a maximum of +125°C. The component is housed in a 28-TQFN-EP package measuring 5x5 mm.

Feature Summary

Integrated multi-rail power solution combining switching and linear regulators
Automotive functional safety certification up to ASIL-C level
Compact surface-mount packaging suitable for space-constrained designs

Applications

Automotive infotainment systems
Advanced driver-assistance systems (ADAS)
Instrument clusters

Procurement Notes

Verify the specific suffix VY+ against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Confirm that the ASIL-C rating aligns with your system's safety integrity requirements before integration. Ensure the 28-TQFN-EP footprint matches your PCB layout constraints.

Selection Notes

Select this component when a single-chip solution is required to manage multiple voltage rails in an automotive environment. It is suitable for designs needing both high-efficiency switching regulation and low-noise linear outputs. Consider the thermal performance of the exposed pad design for heat dissipation needs.

Part Context

This part belongs to the MAX204xx series of automotive power management ICs from Maxim Integrated, now part of Analog Devices. These devices are engineered to reduce bill-of-materials count by integrating multiple regulator types into a single compact package, simplifying board layout and improving reliability in harsh automotive environments.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX204xx family, such as variants with different channel counts or current ratings. Verify compatibility with existing control signals and voltage levels before substituting.
