Infineon Technologies recently launched 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 700-V offering enables designers of high-voltage power stages to simplify their designs while making them more robust.
The new IR7xxxS series of HVICs feature sink/source ratings from 60 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- and 15-V input logic compatible.
The new IR7xxxS series is available in surface-mount (8-SOIC) packages in high volume. The lead-free devices are RoHS-compliant.
