Power Integrations uses FluxLink technology for driver ICs
Adding to Power Integrations’ auto-qualified driver ICs, the company has introduced the automotive-qualified SID1181KQ Scale-iDriver gate driver for 750V-rated IGBTs.
The compact, efficient and robust driver IC uses its high-speed FluxLink communications technology to ensure system safety even during fault conditions. According to Power Integrations, FluxLink technology improves the reliability and isolation capability of the AEC-Q100-qualified gate drivers; it replaces optocouplers and capacitive or silicon-based inductively coupled solutions. Scale-iDriver devices also include protection features such as de-saturation monitoring, primary and secondary under-voltage lock-out (UVLO) and advanced soft shutdown (ASSD) that protect the switch during short-circuit turn-off.
It is intended for use in a wide range of IGBT drivers for electric vehicle (EV) 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, and eliminates tantalum and electrolytic capacitors, futher simplifying the isolated power supply, says Power Integrations. Only one transformer secondary winding is required, advises the company. The use of a simple, two-layer PCB simplifies design further and eases supply-chain management.
The AEC-Q100-qualified Scale-iDriver SID1181KQ gate drivers are available now.
Power Integrations focuses on semiconductor technologies for high-voltage power conversion. The company’s products are key building blocks in the clean-power ecosystem, enabling the generation of renewable energy as well as the efficient transmission and consumption of power in applications ranging from mW to MW.
