MAX25249ATPS/VY+

Overview

The MAX25249ATPS/VY+ is a high-voltage, ASIL-B certified camera PMIC designed for automotive applications. It integrates four synchronous buck converters and one low-dropout regulator (LDO) within a compact 20-pin WETQFN package. The device supports an input voltage range of 4.5 V to 36 V, accommodating standard automotive electrical systems. Output voltages are adjustable from 800 mV to 3.9875 V, with specific channels providing up to 1 A or 1.2 A current capabilities. Operating reliably across a temperature range of -40°C to +125°C, it meets AEC-Q100 standards for robustness in demanding environments.

Feature Summary

• ASIL-B functional safety certification ensures compliance with automotive safety integrity requirements.
• Integrated multi-channel power architecture combines switching regulators and linear regulators for comprehensive system management.
• High-voltage input tolerance allows direct connection to automotive battery rails without external level shifting.

Applications

• Automotive camera module power distribution
• ADAS sensor power supply units
• Vehicle infotainment imaging subsystems

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations such as TPS, ATPC, or BATPE indicate distinct pinouts or thermal characteristics. Confirm availability status directly with authorized distributors, as automotive-grade components often experience allocation constraints. Ensure the selected variant matches the required packaging format and moisture sensitivity level for the intended assembly process.

Selection Notes

Select this component when designing automotive vision systems requiring integrated power sequencing and fault protection. Evaluate the specific output current requirements of the image sensor and ISP to ensure the internal regulators meet load demands. Consider the thermal performance of the WETQFN package relative to the PCB copper area and ambient operating conditions to maintain reliability under continuous load.

Part Context

This part belongs to the MAX25249 family of specialized power management ICs developed for automotive camera applications. It complements other Maxim Integrated solutions by providing a consolidated power stage that reduces board space and component count. The series is engineered to support the evolving power needs of modern automotive imaging sensors while maintaining strict electromagnetic interference limits.
