3-Phase, 600-V ICs Target Inverterized Motor Drives

IR_final-AThe compact IRS2334SPbF and IRS2334MPbF three-phase 600-V ICs for inverterized motor drives are aimed at energy efficient appliance and industrial applications. The IRS2334SPbF is offered in an SOIC20WB package, while the IRS2334MPbF is available in a QFN5X5 package featuring a footprint of just 25 mm2 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) and 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. Both are rated at typical Io+/Io- currents of 200 and 300 mA and a typical turn on and turn off rating of 530 ns. The new ICs utilize IR’s advanced high-voltage IC (HVIC) process, which incorporates high-voltage level-shifting and termination technology to deliver electrical over-stress protection and field reliability. The IRS2334x feature under-voltage lock-out protection, integrated dead-time protection and shoot-through protection. Other features of the new devices include advanced input filtering, a lower di/dt gate driver for better noise immunity, output in phase with inputs and 3.3-V input logic compatibility. Pricing for the IRS2334SPBF begins at $1.95 each/10,000. Production quantities are available immediately. The devices are RoHS compliant.
