Compact, efficient SID1181KQ gate drivers ensure system safety
San Jose, Calif. – January 14, 2020– Power Integrations (Nasdaq: POWI), the leader in gate-driver technology for medium- and high-voltage inverter applications, today announced the launch of its automotive-qualified SID1181KQSCALE-iDriver™gate driver for 750V-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 thereliability and isolation capability of the new AEC-Q100-qualifiedgate drivers,replacing optocouplersand capacitive or silicon-based inductively coupled solutions. SCALE-iDriver devices also include critical protection features such as desaturation monitoring, primary and secondary UndervoltageLock-out (UVLO) and Advanced Soft Shut Down (ASSD) that protect the switch during short-circuitturn-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 fora wide range of IGBT drivers for electric vehicle applications including powertrain, on-boardchargers and charger stations, and other high reliability drivers and inverters.”
SCALE-iDriverICs minimize the number of external components required, eliminatingtantalum and electrolytic capacitors and simplifying the isolated power supply, requiring only one transformer secondary winding. A simple two-layer PCBcan be used, further increasing design simplicity and easing supply-chain management.
Power Integrations’ AEC-Q100-qualified SCALE-iDriverSID1181KQgate drivers are available now, priced at $4.81 in 10,000-piecequantities. Technical informationisavailable from the Power Integrations website at www.power.com/products/scale-idriver-ic-family/sid11xxkq/.
