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.
Michael Hornkamp, Senior Director of Marketing for Automotive Gate-Driver Products at Power Integrations said: “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.
Power Integrations’ AEC-Q100-qualified SCALE-iDriver SID1181KQ gate drivers are available now, priced at $4.81 in 10,000-piece quantities.
