MAX253EUA+T

Power Management - Specialized Overview

The MAX253EUA+T is a primary-side transformer H-bridge gate driver designed for isolated power supply applications. It integrates two drivers with non-inverting configuration, delivering 1 A output current per channel. The device operates on a single supply voltage ranging from 2.5 V to 6 V, with a typical quiescent current of 450 uA. It supports a maximum power dissipation of 727 mW and functions within an operating temperature range of 0°C to +70°C. Packaged in an 8-pin uMAX surface-mount package, it provides efficient control for flyback and forward converter topologies.

Power Management - Specialized Procurement Notes

Verify the specific suffix 'EUA' against the official Analog Devices datasheet to confirm the 8-pin uMAX package variant and commercial temperature grade. Ensure the '+T' designation matches the required reel or cut-tape packaging format for your assembly process. Cross-reference the manufacturer part number directly with the latest product change notices to confirm current production status and availability constraints.

Power Management - Specialized Selection Notes

Select this component when a compact, integrated solution for primary-side H-bridge driving is required without external bootstrap components. Consider the 1 A output capability relative to the gate charge requirements of the target power MOSFETs. Evaluate the 2.5 V to 6 V supply range compatibility with your controller logic levels. Verify that the thermal performance within the uMAX package can handle the expected power dissipation under your specific duty cycle conditions.
