MAX20049DATEE/VY+T

Overview

The MAX20049DATEE/VY+T is an ultracompact power management IC designed for vehicle camera modules. It integrates four power supplies into a tiny footprint, featuring dual buck converters and low-noise LDOs. The device supports a wide voltage input range from 4V to 17V, enabling Power-over-Coax (POC) applications typically operating at 8V to 10V. It offers fault mitigation features to flag output voltage shifts and utilizes spread spectrum with a 2.2MHz switching frequency to mitigate electromagnetic interference.

Feature Summary

• Integrates four power supplies including dual buck converters and low-noise LDOs within a compact form factor.
• Supports wide input voltage ranges suitable for Power-over-Coax implementations in automotive environments.
• Incorporates spread spectrum technology at 2.2MHz to reduce electromagnetic interference emissions.

Applications

• Vehicle camera module power systems
• Power-over-Coax (POC) interfaces
• Automotive sensor and serializer rail generation

Procurement Notes

Verify the specific suffix DATEE against official Analog Devices documentation to confirm pinout and functional compatibility. Confirm availability status as supply constraints may affect lead times. Ensure the component meets required automotive qualification standards before integration into final designs.

Selection Notes

Select this component when designing automotive camera systems requiring high efficiency and minimal board space. The integrated solution reduces external component count compared to discrete alternatives. Verify that the input voltage range aligns with the system's POC or bus architecture requirements.

Part Context

This part belongs to the MAX20049 family of power management ICs developed by Maxim Integrated, now part of Analog Devices. These devices are engineered specifically for automotive vision applications, offering higher efficiency and smaller footprints than competitive quad-power solutions in the same class.

Replacement Considerations

Consult official substitution guides for compatible PMICs. Generic replacements may not match the integrated four-supply configuration or automotive-grade specifications required for camera modules.
