MAX25249ATPH/VY+T

Overview

The MAX25249ATPH/VY+T is an ASIL-B certified mini PMIC for camera sensors. It features a 1A synchronous high-voltage Buck converter with a 4.5V to 36V input range and 3V to 4V output. Two synchronous low-voltage Buck converters provide up to 1.2A each on OUT2 and OUT3, supporting 0.8V to 3.9875V outputs. A fourth LDO output is included. Operating at 2.2MHz switching frequency, it supports -40°C to 125°C temperatures in a 20-WETQFN package.

Feature Summary

• ASIL-B functional safety certification for automotive applications
• Integrated high-voltage buck converter supporting wide input ranges
• Dual low-voltage buck converters delivering high current capacity
• Compact surface-mount packaging with wettable flanks

Applications

• Automotive camera sensor power management
• ADAS vision systems
• In-vehicle imaging modules

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm ASIL-B compliance requirements match your system design. Ensure thermal dissipation capabilities align with the 20-WETQFN footprint constraints. Check lead times as automotive-grade components may have longer availability windows than standard industrial parts.

Selection Notes

Select this component for designs requiring integrated power sequencing for camera sensors. The wide input voltage range accommodates various vehicle battery architectures. Dual buck outputs allow simultaneous powering of different sensor domains. Verify that the 1A and 1.2A current limits meet the peak load requirements of the target image sensors.

Part Context

This part belongs to the MAX25249 family of mini PMICs designed specifically for automotive camera applications. It consolidates multiple regulator functions into a single small-footprint device. The series supports ASIL-B safety standards, making it suitable for critical ADAS functions. It replaces discrete regulator solutions to save board space.

Replacement Considerations

Check for MAX25249 variants with different packaging options such as tray or exposed pad configurations if reel availability is limited. Ensure substitute parts maintain ASIL-B certification and identical pinout compatibility.
