Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The floating logic input is compatible with standard 5V CMOS or LSTTL output. The output driver features a programmable slope control by external R/C and input signals. The floating channels can be used to drive an N-channel power MOSFET or IGBT in the high side configuration, which operates up to 600 volts above the COM ground. www.irf.com © 2008 International Rectifier 3 IRS21956S Simplified Block Diagram VB VDD UVLO UVLO R LIN1 LIN2 Logic and Pulse Generator Pulse R Filter S Q HO3 VS HIN3 VSS Level Shift Down VCC Level Shift Up UVLO Shoot Through Prevention And Logic circuit - Conditioning And Op- amp Driving LO + VSE Reference Generating VREF R Pulse R Filter S Q 10 V regulator COM DV RES www.irf.com © 2008 International Rectifier 4 IRS21956S Typical Connection Diagram A) Linear Ramp driver’s connection diagram B) Stepwise linear Ramp driver’s connection diagram VSET NC VB VDD HO3 LIN1 VS LIN2 NC 5 VDD HIN3 VSS IRS21956 SOW20 Panel NC VCC NC LO NC VSE VREF RES DV COM 25 V Max RRES CREF www.irf.com Optional Cc © 2008 International Rectifier 5 IRS21956S C) Exponential Ramp driver’s connection diagram www.irf.com © 2008 International Rectifier 6 IRS21956S Qualification Information† Qualification Level Moisture Sensitivity Level Machine Model ESD Human Body Model IC Latch-Up Test RoHS Compliant Industrial†† Comments: This family of ICs has passed JEDEC’s Industrial qualification.
