MAX25249BATPA/VY+T

Overview

The MAX25249BATPA/VY+T is a high-efficiency, four-output mini PMIC designed for automotive camera applications. It integrates three DC-DC converters and one high-PSRR LDO within a 20-WETQFN package. The device operates from an input voltage range of 4.5V to 36V. Output 1 provides up to 1A via a synchronous step-down converter. Outputs 2 and 3 deliver up to 1.2A each with adjustable voltages from 0.8V to 3.9875V. Output 4 is a low-noise LDO for imager power. All outputs feature ±1.5% accuracy and overvoltage/undervoltage monitoring.

Feature Summary

Integrates three synchronous buck converters and one high-PSRR LDO in a compact form factor
Includes overvoltage and undervoltage fault monitoring with error communication through the reset pin
Features programmable spread-spectrum frequency modulation to minimize radiated electromagnetic emissions
Compliant with ASIL-B safety ratings for automotive functional safety requirements

Applications

Surround-view cameras
Rear-view cameras
High-megapixel camera systems
Image sensor power supplies

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel configuration. Confirm ASIL-B compliance status and operating temperature range specifications directly from the manufacturer datasheet before integration into safety-critical designs.

Selection Notes

Select this component when a compact solution is required for powering multiple rails in automotive imaging systems. Ensure the input voltage aligns with the 4.5V to 36V operational range. Verify that the integrated current capabilities meet the demands of the target image sensors and serializers.

Part Context

This part belongs to the MAX25249 family of mini PMICs optimized for camera applications. It consolidates multiple power management functions into a single chip, reducing board space compared to discrete solutions. The family supports various output configurations to accommodate different image sensor architectures.
