600-V ICs Target Energy Efficient Inverterized Motor Drive Applications

Fri, 03/16/2012 - 5:51am
600 V ICs motorInternational Rectifier introduced the IRS2334SPbF and IRS2334MPbF three-phase 600V ICs for inverterized motor drives used in 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 25mm2 and designed with the appropriate creepage and clearance requirements to enable rugged and reliable designs at voltages up to 600V. The IRS2334x family provides desirable 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 MOSFET or IGBTs in the high-side configuration. The new ICs utilize IR’s advanced high-voltage IC (HVIC) process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability. The IRS2334x feature under-voltage lock-out protection, integrated deadtime protection and shoot-through protection. Other features include advanced input filter, lower di/dt gate driver for better noise immunity, output in phase with inputs and 3.3V input logic compatibility.
