600-V ICs target motor drive apps

The IRS2334SPbF and IRS2334MPbF are three-phase 600-V 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 25 mm2.

The three-phase IC family provides 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 ICs feature under-voltage lock-out protection, integrated deadtime protection and shoot-through protection. ($1.95 ea/10,000 — available now.)
