Optically Isolated, High Current
MOSFET & IGBT Gate Drivers

TThe IX332B is an advanced 2.5A output current, optically isolated IGBT gate driver. The IX332B offers engineers design flexibility with maximum circuit protection. Features include:

  • VCE desaturation detection
  • UVLO - Under Voltage Lock Out
  • Active Miller clamping
  • 4250Vrms I/O isolation
  • FAULT status output
  • Soft IGBT turn-off

The IX3120 and IX3180 optically coupled gate drivers are capable of sourcing or sinking 2.5A of peak current, which is ideal for driving IGBTs and MOSFETs in the mid-power range. Both devices are ideally suited for use in motor control and inverter applications. Features include:

  • Low input LED current
  • High output peak current
  • High noise immunity
 

FEATURES:
• IEC/EN/DIN EN 60747-5-5 (IX3120GE)
• 2.5A Maximum Peak Output Current
• Wide Operating Voltage Range
• 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
