Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with 5V standard CMOS or LSTTL output. The output driver features a programmable slope control by external R/C and input signal. 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 IRS21856S Simplified Block Diagram VB Conditioning & OPAMP Driving UVLO HO1 R R VSE S Pulse Filter VREF Reference Generating 10V Regulator VS VCC DV 5V Regulator RES UVLO COM LO3 HIN1 HIN2 LIN3 Logic & Pulse Generator www.irf.com © 2008 International Rectifier 4 IRS21856S Typical Connection Diagrams A) Linear Ramp driver’s connection diagram B) Stepwise Linear Ramp driver’s connection diagram www.irf.com © 2008 International Rectifier 5 IRS21856S C) Exponential Ramp driver’s connection diagram VSUS RRES 25V Max VCC VB COM HO1 HIN1 VSE HIN2 IRS21856 SON14 RES LIN3 VS NC DV Optional CC Panel RREF CREF LO3 VREF www.irf.com © 2008 International Rectifier 6 IRS21856S 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.
