IRS2334x Motor Control ICs

International Rectifier presents the compact IRS2334SPbF three-phase 600 V ICs for inverter based motor drives used in energy efficient appliance and industrial applications.

The IRS2334SPbF is offered in an SOIC20WB package and designed with the appropriate creepage and clearance requirements to enable rugged and reliable designs at voltages up to 600 V.

The IRS2334x family provides comprehensive protection including proprietary negative voltage spike (Vs) immunity for safe operation under extreme switching conditions and short circuit events. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use at high frequencies. The floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high-side configuration.

  • Floating channel designed for bootstrap operation
  • Fully operational to +600 V
  • Tolerant to negative transient voltage; dV/dt immune
  • Gate drive supply range from 10 V to 20 V
  • Integrated dead time protection
  • Shoot-through (cross-conduction) prevention logic
  • Matched propagation delay for both channels
  • Lower di/dt gate driver for better noise immunity
  • Under-voltage lockout for both channels
  • Independent three half-bridge drivers
  • 3.3 V input logic compatible
  • Advanced input filter
  • Output in phase with inputs
  • Lead-free, RoHS-compliant
