Highest peak-output gate current; fast shut down; best isolation
SAN JOSE, Calif.--(BUSINESS WIRE)--
Power Integrations (Nasdaq: POWI),
the leader in gate-driver technology for medium- and high-voltage
inverter applications, today announced the SIC1182K
SCALE-iDriver™, a high-efficiency, single-channel silicon carbide (SiC)
MOSFET gate driver that delivers the highest peak-output gate current
available 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; key applications include UPS,
photo-voltaic systems, servo drives, welding inverters and power
supplies.

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. This results in high system
efficiency and enables customers to produce only one design to cover
their entire portfolio of differently rated power inverters. A switching
frequency of up to 150 kHz supports multiple applications.
SCALE-iDriver SIC1182K
SiC gate drivers feature Power Integrations’ high-speed FluxLink™
communications technology, dramatically improving isolation capability.
FluxLink is a revolution in signal transmission, replacing optocouplers
and capacitive or silicon-based solutions, significantly improving
reliability and delivering 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 shutdown within five
microseconds, 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.
Comments Michael Hornkamp, senior director of marketing for gate-driver
products at Power Integrations: “Silicon carbide MOSFET technology opens
the door for decreasing size and weight as well as reduced losses in
power inverter systems. The SCALE-iDriver family with FluxLink™
technology enables safe, cost-effective designs for inverters with very
few external components, ensuring functional safety as well as compact
packaging and maximized efficiency.”
SCALE-iDriver technology minimizes the number of external components
that are needed and reduces the BOM; tantalum or electrolytic capacitors
are not required, and 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.
Power Integrations’ 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.
Devices are available now, priced at $4.65 in 10,000 piece quantities.
