The MAX4426 is a dual‑inverting high‑speed MOSFET driver designed to translate TTL/CMOS inputs to high‑voltage/current outputs. It features a wide supply range (4.5 V‑18 V), low on‑resistance (40 mΩ), fast rise/fall times (≈20 ns with 1000 pF load), and ESD/latch‑up protection. The device is suitable for switching power supplies, DC‑DC converters, motor controllers, and other high‑current applications.
The datasheet includes absolute maximum ratings, detailed electrical characteristics, typical operating curves, recommended bypass capacitors, power‑dissipation formulas, ordering information, and package dimensions for the 8‑lead plastic DIP and CERDIP versions.
