Power Integrations Highly Robust SCALE-iDriver Gate Drivers Achieve AECQ100 Automotive QualificationJanuary 14, 2020 by Power Integrations
This article highlights Power Integrations SID1181KQ SCALE-iDriver™ gate driver for 750 V-rated IGBTs as part of company’s range automotive-qualified ICs.
Compact, efficient SID1181KQ gate drivers ensure system safety
Power Integrations, the leader in gate-driver technology for medium- and high-voltage inverter applications, today announced the launch of its automotive-qualified SID1181KQ SCALE-iDriver™ gate driver for 750 V-rated IGBTs. The new part expands the company’s range of auto-qualified driver ICs, following the introduction of the 1200 V SID1182KQ driver IC.
Compact, efficient and highly robust, the new driver IC uses Power Integrations’ high-speed FluxLink™ communications technology to ensure system safety even during fault conditions. FluxLink technology dramatically improves the reliability and isolation capability of the new AEC-Q100-qualified gate drivers, replacing optocouplers and capacitive or silicon-based inductively coupled solutions. 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.
Comments Michael Hornkamp, senior director of marketing for automotive gate-driver products at Power Integrations: “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.”
SCALE-iDriver ICs 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.
Power Integrations’ AEC-Q100-qualified SCALE-iDriver SID1181KQ gate drivers are available now. Technical information is available from the Power Integrations website at SID11xxKQ.
