Optically Isolated, High Current
MOSFET & IGBT Driver

The IX3120 gate driver includes an input infrared LED that is optically coupled to a power output stage. The power output stage is capable of sourcing or sinking 2A of peak current, which is ideal for driving IGBTs and MOSFETs in the mid-power range.

The gate driver optocoupler with its low input LED current, high output peak current, and high noise immunity (35kV/µs typical) is ideally suited for use in motor control and inverter applications.

The IX3120 is provided in an 8-pin DIP package and an 8-pin Surface Mount package..

 

FEATURES:

• 2.5A Maximum Peak Output Current
• Typical 35kV/µs Common Mode
  Rejection(CMR) at 1500VCM
• Operating Voltage Range: 15V to 30V
• Under-Voltage Lockout with Hysteresis
• 3750Vrms Input to Output Isolation
• Temperature Range: -40C to +100C

APPLICATIONS:

• Isolated IGBT & MOSFET Gate Driver
• Switch Mode Power Supplies
• Industrial Inverters
• Motor Drivers
