Power Integrations has AEC-Q100 automotive-qualified an isolated gate driver for 750V-rated IGBTs. Called SID1181KQ, the device used the firm’s high-speed FluxLink isolation technology, which is based on bond wires and chip-packaging polymer. It “dramatically improves the reliability and isolation capability of gate drivers, replacing optocouplers and capacitive or silicon-based inductively coupled solutions,” claimed the firm. De-saturation monitoring ...
