MAX25249ATPL/VY+

Overview

The MAX25249ATPL/VY+ is a high-voltage, ASIL-B certified camera power management integrated circuit (PMIC) designed for automotive applications. It features four regulated outputs: three synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 5V to 36V and supports a switching frequency of 2.2MHz. Output configurations include one high-current buck channel capable of delivering up to 1A at voltages between 3V and 5V, and two additional buck channels providing up to 1.2A each within the 0.8V to 3.9875V range. The component is housed in a 20-WETQFN package with wettable flanks, ensuring reliable surface-mount assembly.

Feature Summary

• ASIL-B functional safety certification for automotive camera systems
• Integrated high-voltage synchronous buck topology for efficient power conversion
• Wettable flank package design to enhance solder joint inspection reliability

Applications

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

Procurement Notes

Verify the specific suffix 'PL' against the manufacturer's official datasheet to confirm output configuration and pinout compatibility. Ensure the selected variant meets the required ASIL-B integrity level for your target application. Confirm that the 20-WETQFN package dimensions align with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when designing for automotive cameras requiring ASIL-B compliance and high input voltage tolerance. Compare the MAX25249ATPL/VY+ with other variants in the MAX25249 family to ensure the specific output current ratings and voltage ranges match the sensor requirements. Consider the thermal performance of the exposed pad package under maximum load conditions.
