Power Integrations has expanded its SCALE-iDriver family of galvanically isolated single-channel gate driver ICs. The newly added devices support IGBT blocking voltages up to 1700 V, which are generally used in 400 VAC and 690 VAC line applications. They are also ideal for the latest three-level topology PV inverters and for PV arrays leveraging the new 1500 V DC bus standard.

The expanded 1700 V SCALE-iDriver family allows OEMs to use the same highly integrated, safe and reliable driver technology across a range of solutions.

The 1700 V SCALE-iDriver ICs, optimized for driving both IGBTs and MOSFETs, combine Power Integrations' FluxLink magneto-inductive bi-directional communications technology with its SCALE power device driver technology. FluxLink eliminates the need for unreliable opto-electronics and the associated compensation circuitry, thereby enhancing operational stability while reducing system complexity, and SCALE technology incorporates all key gate driver functions into an ASIC, reducing size and improving reliability while simplifying design. Innovative eSOP package features greater than 9.5 mm of creepage and a CTI of 600, according to the company.

The 1700 V SCALE-iDriver ICs can be operated from -40 degrees C to +125 degrees C and at frequencies of up to 75 kHz. The family meets the upcoming requirements of IEC 60747-17 and VDE 0884-17, the vendor said.
