Efficient and Robust IGBT Gate Driver with Automotive Qualification

Hits: 5

The new AEC-Q100 automotive-qualified SID1181KQ SCALE-iDriver gate driver is compact, efficient and highly robust, and it uses high-speed FluxLink communication technology to ensure system safety in various critical conditions. The FluxLink communication technology replaces the Optocouplers and capacitive or silicon-based inductively coupled solutions.

This improves the reliability and isolation capability of the driver IC.
The ICs minimize 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 easy supply-chain management.

The SCALE-iDriver devices also include 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.

Power Integrations’ AEC-Q100-qualified SCALE-iDriver SID1181KQ gate drivers are available now priced at $4.81 in 10,000-piece quantities. Find more information about the SCALE-iDriver ICs, visit the official website of Power Integrations.
