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 Filter R 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 R Pulse Filter R S Q 10 V regulator VREF 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 HO3 VS NC IRS21956 SOW20 NC VCC LO VSE RRES VREF DV RES COM 5 VDD VDD LIN1 LIN2 HIN3 VSS NC NC Panel 25 V Max CREF Optional Cc www.irf.com © 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.
