Description

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.

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.
