This selection guide provides an overview of Infineon's industrial and general-purpose gate driver ICs. These devices are crucial for controlling power switches like MOSFETs and IGBTs, enabling efficient and reliable operation in a wide range of applications.
Infineon Gate Driver IC Technologies
Infineon offers several advanced technologies to meet diverse application needs:
- Junctional Isolation (LS-JI): A mature, industry-standard technology using HVIC and CMOS processes. It enables rugged monolithic construction and offers the best price-performance ratio for high-voltage and low-voltage circuitry. Key benefits include high current capability and precision analog circuitry.
- Silicon-on-Insulator (LS-SOI): An advanced technique using a buried oxide layer for isolation. It provides excellent immunity to negative transients, low-ohmic integrated bootstrap diodes for reduced power losses, and improved driver efficiency. It is ideal for applications requiring high reliability and robustness.
- Coreless Transformer (CT): This technology uses on-chip transformers for galvanic isolation, enabling very large voltage swings (e.g., ±1200 V). It offers immunity against transients, increased product reliability, and low losses.
- Non-Isolated (NI): Utilizes low-voltage circuitry for high-current gate drivers in applications demanding high power density.
