July 2, 2015, Seoul - Infineon Technologies (Korea CEO Lee Seung-soo) has launched a reliable and robust 700V high-voltage IC (HVIC) product family optimized for photovoltaic, power supply, uninterruptible power supply (UPS), welding, and industrial drive applications. This 700V product family enables high-voltage power stage designers to easily implement more robust designs.

Ahmed Masood, head of the high-voltage IC division at Infineon's industrial power control business unit, stated, "The newly launched IR7xxxS 700V HVIC series is the industry's simplest, most compact and most cost-effective solution capable of driving up to 700V MOSFETs or IGBTs, and can reduce component count by up to 30% and board space by up to 50% compared to discrete optocoupler or transformer-based solutions. Additionally, it provides higher breakdown voltage and robust performance in transition regions, thereby improving reliability."

The new IR7xxxS HVIC series features sink/source ratings ranging from 60mA to 2,300mA and employs PN junction technology. Available in half-bridge and high/low-side configurations, the new HVIC is optimized for 700V MOSFETs and 650V IGBTs, and can deliver full driver performance with very fast switching speeds, reducing the number of magnetic components.

Other key features of the new product include low-voltage lockout protection provided on both channels and a low di/dt gate driver that improves noise immunity. Additionally, the HVIC tolerates negative transient voltage dv/dt, provides matched propagation delay on both channels, and is compatible with 3.3V and 15V input logic.

Availability

The new IR7xxxS series is available in surface-mount (8-SOIC) packages and is currently in volume production. Devices comply with lead-free and RoHS requirements.
