New SCALE-iDriver SiC Gate Driver

Power Integrations announced at embedded world in Nuremberg the SIC1182K SCALE-iDriver™, a single-channel SiC MOSFET gate driver that delivers high peak output gate current without an external boost stage. Devices can be configured to support different gate-drive voltage requirements matching the range of requirements seen in SiC MOSFETs today and also include advanced safety features making them both compact and robust. The SIC1182K offers up to 8 A output at a junction temperature of 125°C allowing these devices to support SiC-MOSFET inverter designs up to several hundred kilowatts without a booster stage. A switching frequency of up to 150 kHz supports multiple applications.

SCALE-iDriver SIC1182K SiC gate drivers feature high speed communications FluxLink™ technology, improving isolation capability replacing optocouplers and capacitive or Silicon-based solutions, significantly improving reliability and delivers reinforced isolation up to 1200 V. SCALE-iDriver devices also include system-critical protection features such as desaturation monitoring and current SENSE read out, primary and secondary undervoltage lock-out (UVLO) and Advanced Active Clamping (AAC). More, the protection circuits provide safe shut down within 5 µs, meeting the fast protection needs of SiC devices. SIC1182K SiC gate drivers exhibit high external magnetic field immunity, featuring a package that provides ≥9.5 mm of creepage and clearance, using material that has the highest CTI level, CTI600, to IEC60112. SCALE-iDriver minimizes the number of external components - tantalum or electrolytic capacitors are not required; only one secondary winding is needed. A two-layer-PCB can be used which increases design simplicity, cuts component count and eases supply chain management.

 

SCALE-iDriver SIC1182K SiC gate drivers meet IEC60664-1 isolation coordination for low voltage equipment below 1000 V and IEC61800-5-1 electric motor drive inverter regulations. UL 1577, 5 kVAC for 1 min, is pending and VDE0884-10 is in process. AS
