MAX25249ATPAV/VY+T

Overview

The MAX25249ATPAV/VY+T is a specialized Power Management IC (PMIC) designed for automotive camera applications, certified to ASIL-B safety standards. It integrates four synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 4.5 V to 36 V. Output voltages are adjustable from 800 mV to 3.9875 V for the switching regulators, while the LDO supports outputs from 3 V to 5 V. The component utilizes a 20-WETQFN package with wettable flanks for enhanced soldering reliability.

Feature Summary

• ASIL-B certified power management solution tailored for high-reliability automotive camera sensor systems
• Integrates multiple power conversion topologies including synchronous buck and linear regulators within a single compact footprint
• Features wettable flank package design to improve solder joint inspection and mechanical connection strength

Applications

• Automotive camera sensor power supply
• Advanced driver assistance systems (ADAS) imaging modules
• In-vehicle infotainment camera interfaces

Procurement Notes

Verify the specific suffix 'AV' against official Analog Devices documentation to confirm pinout and functional compatibility, as variations exist within the MAX25249 family. Ensure the component meets ASIL-B requirements for your target application. Confirm availability status directly with authorized distributors, as supply constraints may apply to this specialized automotive part number.

Selection Notes

Select this component when designing automotive vision systems requiring ASIL-B compliance. The integrated topology reduces external component count compared to discrete solutions. Evaluate the thermal performance of the 20-WETQFN package against system heat dissipation capabilities. Ensure the input voltage range aligns with the vehicle's power bus specifications.

Part Context

This part belongs to the MAX25249 series of mini PMICs developed by Maxim Integrated, now part of Analog Devices. The series targets the growing demand for compact, safe power solutions in autonomous driving and ADAS architectures. Variants within the family differ in output configurations and safety certification levels.

Replacement Considerations

MAX25249BATPE/VY+T and MAX25249BATPB/VY+T are documented variants within the same product family. Verify if the alternative suffixes meet the specific ASIL-B requirements and pinout configuration needed for the design.
