Power Integrations has launched an automotive-qualified gate driver for 750 V-rated IGBTs.

The SID1181KQ SCALE-iDriver expands the company’s range of auto-qualified drivers, following the introduction of the 1200 V SID1182KQ.

The gate drivers use Power Integrations’ high-speed FluxLink communications technology to ensure system safety even during fault conditions. FluxLink technology improves the reliability and isolation capability of the new AEC-Q100-qualified gate drivers by replacing optocouplers and capacitive or silicon-based inductively coupled solutions. The SCALE-iDriver devices also include critical protection features such as desaturation monitoring, primary and secondary Undervoltage Lock-out (UVLO) and Advanced Soft Shut Down (ASSD) that protect the switch during short-circuit turn-off.

The SCALE-iDriver devices minimize the number of external components required, eliminating tantalum and electrolytic capacitors and simplifying the isolated power supply, requiring only one transformer secondary winding. A simple two-layer PCB can be used, further increasing design simplicity and easing supply-chain management.

“The SCALE-iDriver family with FluxLink technology supports safe, cost-effective designs for a wide range of IGBT drivers for electric vehicle applications including powertrain, on-board chargers and charger stations, and other high reliability drivers and inverters,” said Michael Hornkamp, senior director of marketing for automotive gate-driver products at Power Integrations.

The AEC-Q100-qualified SCALE-iDriver SID1181KQ gate drivers are available now, priced at $4.81 in 10,000-piece quantities.
