MAX25249ATPAA/VY+

Overview

The MAX25249ATPAA/VY+ is a high-voltage, ASIL-B qualified camera power management IC (PMIC) manufactured by Analog Devices Inc. It integrates 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 voltages are adjustable from 800 mV to 3.9875 V for the switching regulators, while the LDO provides a fixed output between 3 V and 4 V at up to 1 A. The switching frequency is set at 2.2 MHz. It is housed in a 20-WETQFN package rated for operating temperatures from -40°C to 125°C.

Feature Summary

ASIL-B functional safety compliance for automotive camera applications
Integrated topology combining three synchronous buck converters and one LDO
High-voltage input capability supporting wide automotive supply ranges

Applications

Automotive surround view systems
Advanced driver assistance systems (ADAS)
In-vehicle camera modules

Procurement Notes

Verify the specific suffix against official documentation, as variations such as BATPA or ATPC exist within the same family. Confirm availability status directly with the manufacturer or authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when designing automotive vision systems requiring integrated power regulation with functional safety certification. The combination of multiple buck outputs and an LDO simplifies board layout compared to discrete solutions. Consider the 2.2 MHz switching frequency for optimizing external inductor size while managing electromagnetic interference requirements in dense vehicle architectures.

Part Context

This part belongs to the MAX25249 series of specialized PMICs designed specifically for automotive imaging. It addresses the power delivery needs of modern camera sensors and processing units. The series emphasizes reliability and safety compliance, distinguishing it from general-purpose power management devices used in industrial or consumer electronics.
