MAX25249ATPN/VY+T

Overview

The MAX25249ATPN/VY+T is a high-voltage, ASIL-B certified mini Power Management IC (PMIC) designed for automotive camera applications. It integrates four synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 5V to 36V. It features a switching frequency of 2.2MHz and is housed in a compact 20-pin WETQFN package with exposed pad and wettable flanks for enhanced thermal performance and solderability.

Feature Summary

• ASIL-B functional safety compliance for automotive camera systems
• Integrated multi-output topology combining four synchronous buck regulators and one LDO
• Compact footprint utilizing 20-WETQFN package with wettable flank technology

Applications

• Automotive surround view camera systems
• Advanced driver assistance system (ADAS) imaging modules
• High-voltage automotive sensor power distribution

Procurement Notes

Verify the specific suffix PN against official Analog Devices documentation to confirm pinout and thermal pad configuration. Confirm ASIL-B certification status and operating temperature range requirements match the target application environment before finalizing component selection.

Selection Notes

Select this component when designing automotive vision systems requiring integrated power regulation within strict spatial constraints. Ensure the design supports the 2.2MHz switching frequency and utilizes the exposed pad for adequate heat dissipation in enclosed vehicle environments.

Part Context

This part belongs to the MAX25249 family of mini PMICs optimized for automotive imaging. It consolidates multiple power rails into a single solution, reducing board space compared to discrete regulator implementations while maintaining automotive reliability standards.

Replacement Considerations

Consult official cross-reference data for direct substitutes. Verify that any alternative maintains ASIL-B integrity and compatible output configurations.
