Power Integrations announced the launch of its automotive-qualified SID1181KQ SCALE-iDriver gate driver for 750 V-rated IGBTs. The driver IC uses the company’s high-speed FluxLink communications technology for system safety, even during fault conditions. FluxLink technology replaces optocouplers and capacitive or silicon-based inductively coupled solutions.
SCALE-iDriver devices also include protection features such as desaturation monitoring, primary and secondary Undervoltage Lock-out (UVLO), and Advanced Soft Shut Down. The devices minimize the number of external components required, eliminating tantalum and electrolytic capacitors and simplifying the isolated power supply, requiring only one transformer secondary winding, on a two-layer PCB. The SCALE-iDriver SID1181KQ gate drivers are available now, priced at $4.81 in 10,000-piece quantities.
