MAX5064AATC

Overview

The MAX5064AATC is a high-speed half-bridge gate driver IC designed for driving power MOSFETs in demanding applications. It features independent inverting and non-inverting inputs, allowing flexible control configurations. The device supports a maximum bootstrap voltage of 125V and provides peak output currents of 2A for both sourcing and sinking operations. Packaged in a compact 12-TQFN (4x4 mm) format with an exposed pad for thermal management, it integrates protection features to ensure reliable operation in high-frequency switching environments.

Feature Summary

• Provides independent inverting and non-inverting input channels for versatile logic interface compatibility
• Delivers robust 2A peak source and sink current capability for rapid MOSFET switching
• Supports high-side operation with a maximum bootstrap voltage rating of 125V
• Utilizes a thermally enhanced 12-TQFN package with an exposed pad for efficient heat dissipation

Applications

• High-frequency DC-DC converter topologies requiring isolated or floating gate drive
• Motor control systems utilizing half-bridge configurations for phase leg driving
• Industrial power supplies needing high-speed switching with integrated protection

Procurement Notes

Verify the specific suffix variant, as the base model may be obsolete while tape-and-reel versions like MAX5064AATC+T remain available. Confirm the manufacturer status directly with Analog Devices or authorized distributors, as supply chain availability for this component family varies. Ensure the ordering part number matches the required packaging and lead time specifications before finalizing procurement.

Selection Notes

Select this component when a half-bridge driver with independent control inputs is required for high-voltage applications up to 125V. The 2A drive strength suits medium-power MOSFETs where fast switching transitions are critical. Consider the 12-TQFN package constraints for PCB layout and thermal design. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA signals.

Part Context

This device belongs to the MAX5064 series of half-bridge gate drivers from Maxim Integrated, now part of Analog Devices. The series is engineered for high-performance power conversion applications. The AATC designation indicates the automotive-grade temperature range and the specific TQFN package configuration used in compact power modules.

Replacement Considerations

Publicly confirmed substitutes include the MAX5064AATC+T. Verify pinout compatibility and electrical specifications against the original datasheet before substitution. Other variants within the MAX5064 family may offer similar functionality but require validation of input types and voltage ratings.
