MAX25249ATPAV/VY+

Overview

The MAX25249ATPA/VY+ is a high-voltage, ASIL-B certified camera power management IC (PMIC) designed for automotive applications. It integrates four output channels: three 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 specifications include a fixed 1 A channel at 3 V to 4 V, and two adjustable channels ranging from 0.8 V to 3.9875 V with 1.2 A current capability. The LDO provides 1 A at 3 V to 5 V. It utilizes a 20-WETQFN package.

Feature Summary

• ASIL-B functional safety certification for automotive camera systems
• Integrated multi-channel topology combining synchronous buck and LDO regulators
• High-voltage operation supporting wide automotive input ranges

Applications

• Automotive camera sensor power supply
• ADAS vision system power management
• Vehicle infotainment camera interfaces

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations such as 'BATPE' or 'BATPA' exist within the family. Confirm availability status directly with the manufacturer or authorized distributors, as supply constraints may apply. Ensure the specific thermal pad configuration matches the target PCB layout requirements.

Selection Notes

Select this component when ASIL-B compliance is mandatory for the camera power domain. Compare against the MAX25249B series if different output configurations are required. Verify that the 20-pin WETQFN footprint aligns with the design constraints. Ensure the input voltage profile remains within the specified 4.5 V to 36 V operational window.

Part Context

This part belongs to the MAX25249 family of specialized PMICs developed by Maxim Integrated, now part of Analog Devices. These devices are engineered specifically for the stringent reliability and safety standards of modern automotive imaging systems, offering integrated power solutions in compact packages.

Replacement Considerations

The MAX25249BATPA/VY+ is a documented variant within the same product family. Verify pin compatibility and specific output current ratings before substitution.
