MAX25249BATPB/VY+

Overview

The MAX25249BATPB/VY+ is a specialized automotive power management integrated circuit (PMIC) designed for camera sensor applications. It operates within an input voltage range of 4.5 V to 36 V and features four output channels: three synchronous buck converters and one low-dropout regulator (LDO). The switching frequency is fixed at 2.2 MHz. Output specifications include Channel 1 providing 3 V to 4 V at 1 A, while Channels 2 and 3 deliver adjustable voltages from 0.8 V to 3.9875 V at 1.2 A each. The device is housed in a 20-WETQFN package with exposed pad.

Feature Summary

• ASIL-B functional safety compliance for automotive camera systems
• Integrated topology combining synchronous buck regulators and LDO
• High-voltage input capability suitable for automotive environments
• Compact surface-mount packaging with wettable flanks

Applications

• Automotive camera sensor power supply
• ADAS vision system power management
• ASIL-B compliant vehicle electronics

Procurement Notes

Verify the specific suffix 'B' against official Analog Devices documentation to confirm the exact channel configuration and current ratings. Ensure the 'VY+' designation matches the required lead-free and RoHS compliance standards. Confirm the tape-and-reel packaging format aligns with automated assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when designing automotive camera interfaces requiring ASIL-B certification. The device integrates multiple regulation stages, reducing external component count compared to discrete solutions. Verify that the 2.2 MHz switching frequency fits the electromagnetic interference constraints of the target application board layout.

Part Context

This part belongs to the MAX25249 family of mini PMICs developed by Maxim Integrated, now part of Analog Devices. These components are engineered specifically for high-reliability automotive imaging applications. The series addresses the need for compact, efficient power delivery in space-constrained vehicle modules.

Replacement Considerations

MAX25249BATPE/VY+T offers similar functionality but includes four synchronous buck outputs instead of three buck and one LDO.
