SIC118xKQ

Single Channel SiC MOSFET and IGBT Gate Driver with Advanced Active Clamping and Reinforced Isolation for Automotive Applications

Typical Application Schematic

データ シート

製品詳細

SIC1181KQ and SIC1182KQ are single channel gate drivers for SiC MOSFETs. Reinforced galvanic isolation is provided by Power Integrations’ revolutionary solid insulator FluxLink technology. Up to ±8 A peak output drive current enables the product to drive devices with nominal currents of up to 600 / 800 A (typical).

Additional features such as undervoltage lock-out (UVLO) for primary-side and secondary-side, and rail-to-rail output with temperature and process compensated output impedance, guarantee safe operation even in harsh conditions.

SIC118xKQ also features short-circuit protection (at and during turn-on phase), and overvoltage limitation through Advanced Active Clamping (at turn-off phase) via a single sensing pin. For SIC MOSFETs with a current-sense terminal, adjustable over-current detection can be realized.
