MAX25249ATPA/VY+T

Overview

The MAX25249ATPA/VY+T is a high-voltage, ASIL-B qualified mini PMIC designed for automotive camera sensors. It integrates four output regulators: three synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 5V to 36V. Output capabilities include adjustable voltages from 0.8V to 3.9875V at up to 1.2A for the buck channels, and 3V to 5V at 1A for the LDO. It utilizes a 2.2MHz switching frequency and is housed in a 20-WETQFN package with wettable flanks.

Feature Summary

ASIL-B functional safety compliance for automotive applications
Integrated multi-regulator topology combining synchronous buck and LDO outputs
High-voltage input tolerance suitable for automotive power systems
Wettable flank package design for enhanced solder joint inspection

Applications

Automotive camera sensor power supply
ADAS vision system power management
In-vehicle imaging module regulation

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm ASIL-B qualification status matches project requirements. Ensure compatibility with 20-WETQFN footprint during PCB layout. Check for RoHS3 compliance documentation. Validate lead time availability as automotive-grade components may have restricted supply chains.

Selection Notes

Select this component when ASIL-B certification is mandatory for camera power stages. Choose over non-qualified alternatives if functional safety integrity levels are required. Consider the integrated buck/LDO mix to reduce external component count. Verify input voltage ranges align with vehicle battery architectures. Evaluate thermal performance within the 20-WETQFN enclosure constraints.

Part Context

This part belongs to the MAX25249 family of mini PMICs optimized for automotive imaging. It serves as a specialized power solution for camera sensors requiring multiple regulated rails. The series emphasizes compact form factors and high reliability in harsh automotive environments.
