IX6611
IGBT Gate Driver
Features
Description
• Input Compatible with Pulse Transformer
• 10A Peak Source and Sink Current Gate Drive
• Separate Source and Sink Outputs
• Negative Gate Drive Capability
• Over Current Protection
The IX6611 is a secondary side, intelligent, high
speed gate driver designed to drive IXYS IGBTs as
well as power MOSFET devices. The IX6611 gate
driver contains the necessary circuit blocks for pulse
transformer isolated applications. High frequency,
narrow pulses are used for bidirectional data transfer
across the isolation boundary to avoid duty cycle
restrictions and to prevent transformer saturation. The
IX6611 includes the necessary monitor/protection
functions such as Supply Under Voltage Lockout,
Supply Over Voltage Lockout, Thermal Shut down,
external IGBT Over Current and Over Voltage
protection.
with Adjustable Blanking Time
• Advanced Active Clamping Protection
• Under Voltage Lockout Protection
• Over Voltage Lockout Protection
• Two One-Amp Pulse Transformer drivers
for Fault Communication
Applications
• AC and DC Motor Drives
• UPS Systems
• High Voltage DC/DC Converters
The IX6611 is designed to operate over a temperature
range of -40°C to +125°C. The IX6611 is available in a
16-lead SOIC with an exposed thermal pad.
