MAX25249ATPX/VY+T

Overview

The MAX25249ATPX/VY+T is a specialized Power Management IC (PMIC) designed for automotive camera sensors, certified to ASIL-B safety standards. It operates within an input voltage range of 4.5V to 36V and provides four regulated outputs: three synchronous buck converters and one low-dropout regulator (LDO). The device integrates internal switches and supports a switching frequency of 2.2MHz. It is housed in a compact 20-pin WETQFN package with exposed copper pads, suitable for surface-mount installation in high-reliability environments.

Feature Summary

• ASIL-B functional safety certification for automotive applications
• Integrated multi-channel power management combining synchronous buck and LDO regulators
• Compact footprint optimized for space-constrained sensor modules

Applications

• Automotive camera sensor power supply
• ADAS vision system power management
• High-voltage automotive electronics

Procurement Notes

Verify the specific suffix 'TPX' against official Analog Devices documentation, as standard listings typically reference 'BATPE' or 'BATPB'. Confirm RoHS compliance status and lead times directly with authorized distributors due to potential supply constraints. Ensure the component matches the required ASIL-B qualification for your target application.

Selection Notes

Select this PMIC when designing automotive camera systems requiring integrated power regulation and functional safety compliance. It consolidates multiple voltage rails into a single solution, reducing bill-of-materials complexity compared to discrete regulator designs. Verify that the 36V maximum input rating aligns with your vehicle's electrical architecture.

Part Context

This component belongs to the MAX25249 family of mini PMICs developed by Maxim Integrated, now part of Analog Devices. These devices are engineered specifically for the automotive industry to meet stringent reliability and safety requirements. The series offers various output configurations tailored for different sensor types.

Replacement Considerations

Check for MAX25249BATPE/VY+T or MAX25249BATPB/VY+T as potential equivalents. Verify pin compatibility and output specifications before substitution.
