MAX25249ATPL/VY+T

Overview

The MAX25249ATPL/VY+T is a specialized Power Management IC (PMIC) designed for automotive camera systems, certified to ASIL-B safety standards. It integrates four synchronous buck converters and one low-dropout regulator (LDO) within a compact 20-pin WETQFN package. The device operates from an input voltage range of 4.5 V to 36 V. Output capabilities include three adjustable buck channels ranging from 800 mV to 3.9875 V with up to 1.2 A current, one fixed 3 V to 5 V buck channel rated at 1 A, and one LDO output. This integration supports complex power sequencing requirements in high-voltage automotive environments.

Feature Summary

• Integrated multi-channel power management combining four synchronous buck regulators and one linear regulator for comprehensive system power distribution.
• Automotive-grade design compliant with ASIL-B functional safety standards for reliable operation in demanding vehicle environments.
• Wide input voltage tolerance supporting direct connection to high-voltage automotive battery rails without external level shifting.

Applications

• Automotive surround-view camera systems
• Advanced driver-assistance system (ADAS) sensor modules
• In-vehicle infotainment camera interfaces

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pin compatibility and thermal characteristics. Confirm availability status as supply constraints may apply. Ensure the selected variant matches the required output configuration and safety certification levels for the target application.

Selection Notes

Select this component when designing camera subsystems requiring integrated power sequencing and ASIL-B compliance. Evaluate the total output current requirements against the individual channel limits. Consider the thermal performance of the exposed pad TQFN package relative to the PCB copper area available for heat dissipation.

Part Context

This part belongs to the MAX25249 family of mini PMICs developed by Maxim Integrated, now part of Analog Devices. These devices are engineered specifically to reduce board space and simplify power architecture for automotive imaging applications by consolidating multiple regulators into a single small-footprint solution.

Replacement Considerations

Consult official cross-reference data for verified substitutes such as the MAX25249BATPE/VY+T or other variants within the MAX25249 series that offer compatible pinouts and electrical specifications.
