Overview
The MAX16922ATPI/V+ is an automotive-grade PMIC featuring two 2.2MHz synchronous buck converters, dual LDOs, and an active-low reset controller. It operates from a 3.7V to 28V input range within a 20-pin TQFN-EP package. The device supports output voltages of 1V, 2.7V, 3.3V, and 5V with currents up to 1.2A for the DC-DC channels. It meets AEC-Q100 standards and functions between -40°C and +125°C.
Feature Summary
- Integrates dual step-down DC-DC converters and dual low-dropout regulators in a single compact package
- Includes an active-low reset controller for system supervision
- Designed for automotive applications with AEC-Q100 qualification
Applications
- Automotive infotainment systems
- Instrument cluster power management
- Telematics control units
- Body control modules
Procurement Notes
Verify component authenticity through authorized distribution channels due to obsolete status. Confirm package marking and datasheet revision against official Analog Devices records. Request lot traceability documentation to ensure compliance with automotive quality standards prior to integration into production designs.
Selection Notes
Evaluate thermal performance requirements given the TQFN-EP package and high switching frequency. Ensure input voltage range compatibility with the vehicle's power bus. Verify that the integrated reset thresholds meet the target microcontroller or processor supervision needs without external components.
Part Context
This component belongs to the MAX16922 family of power management ICs designed specifically for automotive environments. It consolidates multiple power rails into one solution, reducing board space compared to discrete regulator implementations. The series emphasizes reliability and efficiency for critical vehicle electronics.
Replacement Considerations
The part status is listed as obsolete. Check for direct pin-compatible successors within the Maxim Integrated portfolio. Verify if newer generations offer improved efficiency or extended supply chains before finalizing design changes.
