MAX25256ATBA/V+T

Power Management - Specialized Overview

The MAX25256ATBA/V+T is an automotive-grade, synchronous H-bridge transformer driver designed for isolated power supply applications. It operates within a supply voltage range of 8V to 36V and supports junction temperatures from -40°C to 125°C. The device delivers up to 300mA of drive current to the transformer windings. It utilizes a TDFN-10EP package for surface mount installation and holds AEC-Q100 qualification for automotive reliability standards.

Power Management - Specialized Feature Summary

• Integrated H-bridge topology for driving isolation transformers
• Automotive qualification compliant with AEC-Q100 standards
• High current drive capability for efficient transformer excitation

Power Management - Specialized Applications

• Isolated DC-DC converter designs in automotive systems
• Gate driving for high-side and low-side switches in isolated topologies
• Power management modules requiring galvanic isolation

Power Management - Specialized Procurement Notes

Verify the specific suffix 'V+T' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and lead-free status. Ensure the component meets the required AEC-Q100 grade specifications for your target automotive application environment before finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when designing isolated power stages that require a dedicated driver for an external transformer rather than an integrated isolated regulator. Consider the 300mA output current limit and the 8V to 36V input range to ensure compatibility with the system's bus voltage and transformer impedance requirements.

Power Management - Specialized Part Context

This part belongs to Maxim Integrated's portfolio of automotive power management solutions. It serves as a specialized interface between control logic and the magnetic components in isolated power conversion circuits, distinct from standard gate drivers or complete switching regulators.

Power Management - Specialized Replacement Considerations

Consult Analog Devices official documentation for qualified alternate part numbers. Verify pinout compatibility and electrical parameters such as drive current and operating voltage range before substituting.
