MVR5510AMDA0ESR2

Overview

The MVR5510AMDA0ESR2 is an automotive-grade multi-channel high-voltage power management IC from NXP Semiconductors, designed for ASIL-D safety compliance. It integrates multiple high-efficiency synchronous buck regulators on a single die, sharing thermal management through a large exposed pad. The device supports a maximum input voltage of 60 V DC and operates within a temperature range of -40°C to +125°C. Key output capabilities include configurable VPRE synchronous buck controllers with external MOSFETs and configurable single/dual-phase low voltage buck converters. It is housed in a 56-HVQFN (8x8) package.

Procurement Notes

Verify the complete part number including suffixes such as 'ESR2' to ensure correct packaging and tape-and-reel configuration. Confirm ASIL-D qualification status matches specific project safety requirements. Check for available development kits like KITVR5510MA0EVm for initial evaluation. Ensure compatibility with 60V input systems and verify thermal dissipation needs for the QFN56 package in the final enclosure design.

Selection Notes

Select this component when ASIL-D functional safety certification is mandatory for the power management section. Choose this part for applications requiring integrated high-voltage buck regulation with shared thermal management. Consider the 56-pin HVQFN package constraints for PCB layout and heat sinking. Evaluate the need for configurable VPRE and low-voltage buck stages against alternative discrete solutions to optimize bill of materials and board space.

Part Context

The VR5510 series represents NXP's portfolio of multi-channel high-voltage PMIC devices tailored for demanding automotive and industrial environments. This series emphasizes high integration and safety compliance, addressing the complex power distribution needs of modern electronic control units. The MVR5510AMDA0ESR2 variant specifically targets ASIL-D applications, distinguishing itself from lower safety-rated counterparts within the broader family by offering enhanced diagnostic features and fault handling capabilities.

Replacement Considerations

Direct substitutes are limited due to specific ASIL-D requirements. Verify pin-to-pin compatibility if considering other VR5510 variants, but note that safety certifications may differ. Cross-reference with other ASIL-D qualified PMICs from different manufacturers only if electrical specifications and package dimensions align precisely.
