New 1700 V SCALE-iDriver gate driver IC targets applications from 480-690 VAC

SCALE-iDriver galvanically isolated single-channel gate driver ICs now support IGBT blocking voltages up to 1700 V, which are typically used in 480 to 690 VAC line applications. They are ideal for industrial drives, 3-level power supplies/UPS and photovoltaic inverters, commercial EV and traction auxiliary equipment. 1700 V SCALE-iDriver ICs deliver a gate current of up to 8 A to support systems of up to 110 kW without an external booster, and up to 30 A gate current for over 400 kW with an external booster stage.

1700 V SCALE-iDriver ICs, are optimized for driving both IGBTs and MOSFETs and combine Power Integrations’ pioneering FluxLink magneto-inductive bi-directional communications technology with SCALE power device driver technology. The new device family also makes use of the innovative eSOP package which provides greater than 9.5 mm of creepage and a CTI of 600 for high breakdown protection and increased system reliability.

1700 V SCALE-iDriver ICs meet the upcoming IEC 60747-17 and VDE 0884-17 standards. Devices feature desaturation (short-circuit) protection with Advanced Soft Shut Down (ASSD) functionality, providing reliable and easy-to-implement protection to the power switch.
