Power Integrations has unveiled 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 1200V SID1182KQ driver IC.
The new driver IC uses Power Integrations’ FluxLink communications technology to ensure system safety, even during fault conditions. FluxLink technology looks to improve 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.
Michael Hornkamp, senior director of marketing for automotive gate-driver products at Power Integrations comments: “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 minimise 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.
