MAX25249ATPI/VY+

Overview

The MAX25249ATPI/VY+ is a high-voltage automotive power management IC designed for camera applications. It integrates three synchronous buck converters and one low-dropout linear regulator, operating within a 4.5V to 36V supply range. The device supports a switching frequency of 2.2MHz and functions reliably across an ambient temperature range of -40°C to 125°C. Packaged in a compact 20-WETQFN (3.5x3.5mm) with wettable flanks, it meets AEC-Q100 qualification standards.

Feature Summary

• Integrates three synchronous buck regulators and one LDO for multi-rail power distribution
• High-voltage input capability suitable for automotive electrical systems
• Automotive-grade reliability with AEC-Q100 certification
• Compact footprint with wettable flank package for enhanced inspection

Applications

• Automotive camera modules
• Surround view systems
• Advanced driver assistance systems (ADAS)
• In-vehicle infotainment displays

Procurement Notes

Verify the specific suffix ATPI against official Analog Devices documentation to confirm pinout and thermal pad configuration. Confirm AEC-Q100 compliance status directly with the manufacturer or authorized distributors. Ensure the selected package variant matches the PCB land pattern requirements for the 20-WETQFN form factor.

Selection Notes

Select this component when designing power architectures for automotive imaging sensors requiring multiple regulated rails from a single high-voltage source. The integrated topology reduces external component count compared to discrete solutions. Evaluate thermal performance based on the total output current demands of the three buck channels and the LDO under maximum load conditions.

Part Context

This part belongs to the MAX25249 family of high-voltage PMICs optimized for automotive vision systems. It consolidates power regulation functions typically handled by separate controllers into a single chip. The design targets space-constrained automotive environments where board real estate and system reliability are critical constraints.

Replacement Considerations

Consult official cross-reference data for compatible alternatives. Verify that any substitute maintains identical voltage ratings, current capabilities, and package dimensions.
