MAX20049DATEJ/VY+

Overview

The MAX20049DATEJ/VY+ is a fully integrated, ultra-compact power management IC designed for automotive camera modules. It features four independent output channels: two high-efficiency synchronous buck converters and two low-dropout linear regulators (LDOs). The device supports a wide input voltage range of 4V to 17V, accommodating standard automotive supply rails and coaxial cable powering (POC) up to 10V. Operating at a fixed 2.2MHz switching frequency with spread-spectrum modulation, it minimizes electromagnetic interference to meet CISPR standards. Integrated protection mechanisms include overvoltage, undervoltage lockout, thermal shutdown, and cycle-by-cycle current limiting.

Feature Summary

• Integrates dual buck converters and dual LDOs in a minimal 3mm x 3mm QFN package
• Supports flexible input voltages including 8V-10V coaxial cable powering
• Features spread-spectrum modulation to reduce EMI emissions
• Provides comprehensive fault monitoring via PGOOD signals

Applications

• Automotive camera module power distribution
• ADAS imaging system power supplies
• Image sensor and serializer power conditioning
• Coaxial cable powered camera systems

Procurement Notes

Verify the specific suffix DATEJ against official Analog Devices documentation to confirm exact factory-trimmed output voltage configurations. Ensure the component meets AEC-Q100 qualification requirements for your target automotive grade. Cross-reference the datasheet revision history to validate compatibility with your design specifications before finalizing procurement.

Selection Notes

Select this component when board space is constrained and multiple regulated rails are required for camera sensors and serializers. The integrated nature reduces external component count compared to discrete solutions. Verify that the fixed output voltage options provided by the DATEJ suffix align with the specific voltage requirements of your image sensor and serial data links.

Part Context

This part belongs to the MAX20049 family of automotive PMICs. It is distinct from other Maxim Integrated parts like the MAX25249 or MAX20404 series which offer different channel counts or topologies. The MAX20049 is specifically optimized for the high integration needs of modern automotive imaging applications, offering a balance of efficiency and size reduction.

Replacement Considerations

Direct replacements within the same family include variants with different output voltage trims or packaging options. Check the official pin-to-pin compatible list in the datasheet. No cross-family substitutes are confirmed as direct replacements due to unique integration levels.
