MAX16984AATJB/V+T

Overview

The MAX16984AATJB/V+T is an automotive-grade switching voltage regulator designed as a USB-C protector and emulator. It integrates a synchronous buck converter with a fixed 5V output and 2.4A current capability. The device operates at a 2.2MHz switching frequency, enabling compact passive component selection. It supports an input voltage range of 4.5V to 28V and functions within an ambient temperature range of -40°C to +125°C. Packaged in a 32-pin TQFN-EP (5x5mm) format, it meets AEC-Q100 qualification standards for automotive reliability.

Feature Summary

• Integrates USB Type-C protection and emulation logic alongside power conversion
• Features synchronous buck topology for high efficiency
• Qualified for automotive applications under AEC-Q100 standards

Applications

• Automotive infotainment systems requiring USB-C connectivity
• Vehicle charging ports with integrated power management
• Automotive display interfaces utilizing USB-C protocols

Procurement Notes

Verify the specific suffix 'V+T' indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 compliance requirements match your automotive quality standards. Ensure the 32-TQFN footprint aligns with your PCB layout constraints. Cross-reference the datasheet for thermal pad soldering recommendations to ensure reliable operation within the specified temperature range.

Selection Notes

Select this component for designs requiring combined USB-C protocol handling and regulated power delivery in a single package. The fixed 5V output suits standard USB-C power rails. Consider the 2.2MHz frequency for minimizing external inductor size compared to lower-frequency alternatives. Verify that the 2.4A output current meets the load requirements of the connected peripheral devices.

Part Context

This part belongs to the Maxim Integrated automotive power management portfolio, specifically targeting USB-C integration. It combines protection circuitry with DC-DC conversion to simplify system architecture. The TQFN-EP package provides thermal performance suitable for high-density automotive electronics. It serves as a specialized solution for modern vehicle interfaces demanding robust power and data line protection.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX16984 family or similar automotive USB-C controllers from Analog Devices. Verify that any replacement maintains the 2.2MHz frequency and 5V/2.4A specifications. Ensure the alternative component also holds AEC-Q100 qualification if used in safety-critical automotive environments.
