Overview
The MAX25250ATPA/VY+ is an ASIL B Mini PMIC designed for automotive camera sensor power supply. It integrates three synchronous buck converters and one LDO within a compact 20-WETQFN package. The device supports an input voltage range of 5V to 22V and operates reliably across a temperature range of -40°C to +125°C. Certified under AEC-Q100 standards, it features integrated sequencing capabilities to manage power rails efficiently in demanding automotive environments.
Feature Summary
- Integrated ASIL B functional safety compliance for automotive applications
- Combines multiple switching regulators with linear regulation in a single chip
- Includes built-in power sequencing logic for controlled startup and shutdown
Applications
- Automotive camera module power management
- ADAS sensor power distribution networks
- Vehicle infotainment system peripheral supplies
Procurement Notes
Verify the specific suffix VY+ against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the selected variant matches the required ASIL B safety integrity level for your target application. Cross-reference the 20-WETQFN package dimensions with your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when designing automotive vision systems requiring high reliability and space efficiency. The integrated topology reduces external component count compared to discrete solutions. Consider the 2.2MHz switching frequency for optimal inductor size versus EMI performance trade-offs in dense automotive PCB layouts.
Part Context
This part belongs to the Maxim Integrated automotive PMIC family, now under Analog Devices. It addresses the growing demand for miniaturized power solutions in modern vehicles. The series focuses on providing robust power management for sensors and cameras while maintaining strict automotive quality and safety standards.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Do not assume pin-to-pin compatibility with other MAX25xxx variants without explicit datasheet confirmation.
