MAX25249BATPJ/VY+

Overview

The MAX25249BATPJ/VY+ is a high-voltage, ASIL-B qualified mini PMIC designed for camera applications. It integrates three synchronous buck converters and one LDO within a compact 20-WETQFN package. The device supports an input voltage range of 4.5V to 36V. Output capabilities include three buck channels with currents up to 1.2A and one LDO channel rated at 1A. Switching frequencies are configurable, typically operating at 2.2MHz. The component meets AEC-Q100 standards and operates across a temperature range of -40°C to +125°C.

Feature Summary

• ASIL-B functional safety compliance for automotive camera systems
• Integrated topology combining three synchronous buck converters and one linear regulator
• High-voltage input tolerance supporting direct battery connection
• Wettable flank packaging enabling automated optical inspection

Applications

• Automotive surround view camera systems
• ADAS sensor power management
• In-vehicle infotainment camera modules
• Digital camera power distribution networks

Procurement Notes

Verify the specific suffix (PJ vs PC) against the official Analog Devices datasheet to confirm pinout and thermal pad configuration. Confirm ASIL-B qualification status through the manufacturer's quality documentation. Ensure the wettable flank package variant matches the PCB footprint requirements. Check for RoHS3 compliance certificates prior to final procurement approval.

Selection Notes

Select this component when designing camera power stages requiring high-voltage input handling and functional safety certification. The integrated buck-LDO topology reduces external component count compared to discrete solutions. Evaluate the 2.2MHz switching frequency against EMI constraints in the target enclosure. Ensure the 20-WETQFN thermal performance meets the system's heat dissipation requirements under maximum load conditions.

Part Context

This part belongs to the MAX25249 family of mini PMICs optimized for automotive imaging. It replaces multiple discrete regulators with a single integrated solution. The family shares common architectural features but varies in output configurations and package options. The BATJ variant specifically denotes the wettable flank package suitable for high-reliability surface mount assembly processes.

Replacement Considerations

Direct substitutes include other MAX25249 variants such as MAX25249BATPA/VY+ or MAX25249ATPC/VY+, provided the pinout and electrical specifications match the design requirements. Verify that any replacement maintains the same ASIL-B qualification level and package dimensions.
