October 1, 2025 /SemiMedia/ — Littelfuse Inc has launched the IX3407B, a single-channel isolated gate driver designed for high-voltage power applications, including Si/SiC MOSFETs and IGBTs. The device delivers up to 7 A peak source and sink current and incorporates 2.5 kV capacitive isolation to ensure signal integrity and system safety.

The IX3407B features fast propagation delay, high common mode transient immunity (CMTI), and enhanced thermal stability, supporting efficient operation across wide switching frequencies and temperature ranges. Compared to traditional optocoupler or transformer-based isolation, it reduces board space, component count, and system complexity while increasing design flexibility and long-term reliability.

Target applications include AC and brushless DC motor drives, solar inverters, energy storage systems, high-voltage DC/DC converters, LLC and totem-pole PFC stages, induction heating systems, welding equipment, uninterruptible power supplies (UPS), and factory and building automation.

The device comes in a SOIC-8 wide-body package (WB), meets J-STD-020 Moisture Sensitivity Level 1, and supports operation up to 175°C. Samples and production quantities are available through authorized Littelfuse distributors worldwide.
