About

EiceDRIVER? gate driver IC technologies

Thanks to technology development at Infineon and International Rectifier, our selection of gate driver ICs range from simple, cost-effective solutions to full-featured, advanced ICs. Infineon offers two level-shift gate driver IC technologies:

  • Level-shift Silicon-on-insulator (SOI) technology?enables a rugged, high-voltage monolithic IC design. SOI provides low-ohmic, integrated bootstrap-diodes, protection against negative transient voltage spikes, and eliminates parasitic transistors that cause latch-up.
  • Level-shift Junction Isolation (JI) technology (link to Junction Isolation page) is our industry-proven, standard MOS/CMOS process. Our high-voltage integrated circuit (HVIC) and latch-immune CMOS technologies enable monolithic construction with the best price for performance.
Infineon silicon on insulator (SOI) technology

Infineon silicon-on-insulator (SOI) technology is a high-voltage, level-shift technology for gate driver ICs with integrated bootstrap-diode (BSD) and industry-best-in-class robustness to protect against negative transient voltage spikes. Each transistor is isolated by buried silicon dioxide eliminating parasitic bipolar transistors that can cause latch-up. This technology? can also lower the level-shift power losses to minimize device-switching power dissipation. The advanced process allows monolithic high-voltage and low-voltage circuitry construction with technology-enhanced benefits.?

Infineon offers three-phase and half-bridge gate driver ICs that can drive up to 8 A current and withstand voltages for each voltage class: <200 V, 600 V, 650 V, and 1200 V.?

Infineon junction-isolated (JI) technology

Pioneered by International Rectifier (IR) since 1989 with the introduction of the first monolithic product, the high-voltage integrated circuit (HVIC) technology uses patented and proprietary monolithic structures integrating bipolar, CMOS, and lateral DMOS devices with breakdown voltages above 700 V and 1400 V for operating offset voltages of 600 V and 1200 V.

Using this mixed-signal HVIC technology, both high-voltage level-shifting circuits and low-voltage analog and digital circuits can be implemented. With the ability to place high-voltage circuitry (in a 'well' formed by polysilicon rings) that can 'float' 600 V or 1200 V on the same silicon away from the rest of the low-voltage circuitry, high-side power MOSFETs, or IGBTs exist in many popular off-line circuit topologies such as buck, synchronous boost, half-bridge, full-bridge, and three-phase.

These HVIC gate drivers with floating switches are well-suited for topologies requiring high-side, half-bridge, and three-phase configurations.
