700V HVICs Increase System Reliability and Shrink Board Space

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

The new IR7xxxS series of HVICs feature sink/source ratings from 60 mA to 2,300 mA 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. The new IR7xxxS series is available in Surface Mount (8-SOIC) packages in high volume. The devices are lead free and RoHS compliant.
