MAX16922ATPD/V+

Overview

The MAX16922ATPD/V+ is a power management integrated circuit designed for automotive applications. It integrates two 2.2MHz step-down DC-DC converters, dual low-dropout regulators, and an active-low reset controller in a 20-TQFN package. The device supports an input voltage range of 3.7V to 28V with outputs including 1V, 2.7V, 3.3V, and 5V. Output currents reach up to 1.2A for the buck converters and 600mA for LDOs. It operates between -40°C and +125°C and holds AEC-Q100 qualification.

Feature Summary

• Integrates dual high-frequency buck converters and dual LDOs within a single compact footprint
• Includes an active-low reset monitor for system supervision
• Qualified for automotive environments under AEC-Q100 standards

Applications

• Medium power-level automotive electronic systems
• Automotive infotainment units
• Instrument cluster power distribution

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm lot traceability and storage history given age. Ensure compatibility with existing PCB layouts as pinouts may vary across package suffixes. Request original manufacturer documentation for final electrical validation before integration into production designs.

Selection Notes

Evaluate thermal performance requirements for the TQFN package in enclosed automotive enclosures. Verify that the 2.2MHz switching frequency aligns with electromagnetic interference constraints. Check if the fixed output voltages meet load requirements or if adjustable variants are necessary. Assess input voltage stability against the specified 3.7V minimum threshold.

Part Context

This part belongs to the MAX16922 family of PMICs from Maxim Integrated, now part of Analog Devices. The series targets automotive markets requiring consolidated power solutions. Variants differ primarily by package type and temperature grade, sharing core functional architecture.
