MVR5510AMBAHES

Overview

The MVR5510AMBAHES is a safety power management IC from the VR5510 family, designed for automotive applications. It features a multi-output architecture combining synchronous buck controllers and low-dropout regulators (LDOs). The device supports a maximum input voltage of 60 V DC. Key electrical specifications include output currents of 800 mA, 1 A, and 3.6 A, with a maximum output voltage of 5 V. It operates within a temperature range of -40°C to +125°C and is housed in a QFN-56 package.

Feature Summary

• Configurable synchronous buck controller supporting external MOSFETs and single or dual-phase low voltage buck topologies.
• Deep sleep mode functionality that shuts down all regulators except the high-voltage LDO when operating in LDO mode.
• Automotive-grade design compliant with ASIL-B safety requirements.

Applications

• Automotive multi-output power management systems
• Safety-critical electronic control units requiring ASIL-B compliance
• Complex vehicle architectures utilizing SMPS and LDO hybrid regulation

Procurement Notes

Verify the specific suffix HES against official NXP documentation to confirm pinout and feature configuration. Ensure compatibility with the required thermal management solutions for the QFN-56 package. Confirm that the 60 V input rating aligns with the target system's electrical environment. Validate that the 800 mA to 3.6 A output capabilities meet the load requirements of the connected subsystems.

Selection Notes

Select this component for applications requiring integrated safety features and flexible power topology configurations. The combination of configurable buck controllers and LDOs allows for optimized efficiency and noise performance. Consider the QFN-56 footprint for space-constrained designs. Ensure the designer has access to the necessary external components for the synchronous buck stages.

Part Context

This part belongs to the VR5510 series of multi-output PMICs from NXP Semiconductors. The series is engineered for robust automotive environments, offering high integration levels to reduce bill-of-materials complexity.
