MAX25252ATIA/VY+

Overview

The MAX25252ATIA/VY+ is a high-efficiency, five-output power management IC designed for automotive ADAS applications. It integrates three synchronous buck converters capable of delivering up to 1.7A each and two linear regulators rated for 1A output. The device features overvoltage and undervoltage monitoring on all outputs and includes two high-PSRR LDOs. It is qualified to ASIL B standards.

Feature Summary

• Integrates three synchronous buck converters and two linear regulators in a single package
• Provides comprehensive output protection with overvoltage and undervoltage monitoring on all channels
• Includes two low-noise LDOs with high power supply rejection ratio for sensitive loads
• Automotive qualification compliant with ASIL B safety integrity level requirements

Applications

• Advanced Driver Assistance Systems (ADAS) power distribution
• Automotive sensor node power regulation
• Camera module power management
• Radar unit voltage regulation

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity directly with Analog Devices or authorized distributors. Confirm that the component meets current automotive reliability standards and check for any recent lifecycle status updates regarding availability or obsolescence before finalizing procurement plans.

Selection Notes

Select this PMIC when a compact solution is required for multiple voltage rails in ADAS architectures. Ensure the total load current does not exceed the combined capacity of the integrated buck and LDO outputs. Verify that the input voltage range aligns with the vehicle's battery system specifications and that thermal constraints are managed within the application enclosure.

Part Context

This component belongs to the MAX25252 family of high-efficiency, low-voltage PMICs specifically engineered for automotive environments. It consolidates multiple power stages into a single footprint, reducing board space compared to discrete solutions. The series is optimized for the stringent noise and reliability requirements of modern vehicle electronics.
