Infineon’s Rugged Reliable IR7xxxS Series of 700 V HVICs Increases System Reliability and Shrinks Board Space

Munich, Germany – June 23, 2015 – Infineon Technologies AG announced the introduction of a family of rugged, reliable 700V High-Voltage ICs (HVICs) optimized for solar, power supply, uninterruptible power supplies (UPS), welding and industrial drive applications. The 700 V offer-ing enables designers of high-voltage power stages to simplify their design while making them more robust.

“The new IR7xxxS series of 700V HVICs offers the simplest, smallest and lowest cost solution to drive MOSFETs or IGBTs up to a blocking voltage of 700 V, deli-vering 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.

The new IR7xxxS series of HVICs feature sink/source ratings from 60 mA to2,300mA and utilize PN junction technology. Available in half bridge and high- and low-side configurations, the new HVICs are optimized for 700 V MOSFETs and 650 V IGBTs and offer full driver capability with extremely fast switching speeds to reduce magnetics component count.

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.
