MAX16922ATPE/V+T

Overview

The MAX16922ATPE/V+T is an automotive-grade Power Management IC (PMIC) from Analog Devices/Maxim Integrated, designed for high-efficiency power conversion in demanding environments. It integrates two independent 2.2 MHz synchronous buck DC-DC converters and two low-dropout (LDO) regulators within a single package. The device supports an input voltage range of 3.7 V to 28 V and delivers output currents up to 1.2 A for the switching regulators and 300 mA for the LDOs. It features fixed output voltages of 1 V, 2.7 V, 3.3 V, and 5 V, with a load regulation of ±0.2%. Operating reliably between -40°C and +125°C, it is qualified to AEC-Q100 standards and housed in a compact 20-pin TQFN-EP package.

Feature Summary

• Integrates dual step-down DC-DC converters and dual LDOs for comprehensive power management
• High-frequency 2.2 MHz switching operation enables reduced passive component size
• Automotive qualification ensures reliability under extreme temperature conditions
• Includes active-low reset functionality for system protection

Applications

• Automotive infotainment systems
• Digital cockpit displays
• Telematics control units
• ADAS sensor power supplies

Procurement Notes

Verify the specific suffix 'V+T' indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 qualification status is required for your automotive application. Check current availability as distribution may be limited or subject to allocation. Ensure the 20-TQFN footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when a single IC solution is needed for multiple voltage rails in automotive electronics. It is suitable for designs requiring high efficiency at light loads due to the 2.2 MHz frequency. Consider the 28 V maximum input rating for standard 12 V automotive systems with load dump conditions. Verify that the integrated LDOs meet the noise sensitivity requirements of downstream analog circuits.

Part Context

This part belongs to the MAX16922 family of automotive PMICs. It shares functional similarities with other Maxim Integrated buck converter families but is distinct in its integration of dual switches and dual LDOs. The 'ATPE' designation specifies the automotive temperature grade, plastic package type, and reel packaging format within the broader product line.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly confirmed in public documentation. Evaluate alternatives like the MAX16922ATPK/V+ for tube packaging differences or the MAX16922ATPA-V- for potential legacy compatibility. Always verify electrical parameters and thermal performance against the original datasheet before substitution.
