Infineon Technologies AG has announced the introduction of a family of rugged, reliable 700 V High-Voltage ICs (HVICs) optimized for solar, power supply, uninterruptible power supplies (UPS), welding and industrial drive applications. The 700V offering enables designers of high-voltage power stages to simplify their design while making them more robust.

“The new IR7xxxS series of 700-Volt HVICs offers the simplest, smallest and lowest cost solution to drive MOSFETs or IGBTs up to a blocking voltage of 700 Volts, delivering up to 30 percent reduction in part count and up to 50 percent of board space compared to discrete optocoupler or transformer-based solutions. Moreover, the devices deliver higher breakdown voltage and rugged transient performance for increased reliability,” said Ahmed Masood, Executive Director of High-Voltage ICs at Infineon’s Industrial Power Control Division.

Other key features of the new devices include under-voltage lock-out protection for both channels, lower di/dt gate driver for better noise immunity. In addition, the HVICs are tolerant to negative transient voltage dv/dt, offer matched propagation delay for both channels and are 3.3 V and 15 V input logic compatible. The new IR7xxxS series is available in Surface Mount (8-SOIC) packages in high volume. The devices are lead free and RoHS compliant.
