Data Sheet No. PD60177 Rev. F IR4426/IR4427/IR4428(S) & (PbF) DUAL LOW SIDE DRIVER Features Product Summary Gate drive supply range from 6 to 20V CMOS Schmitt-triggered inputs Matched propagation delay for both channels I +/- 1.5A / 1.5A O Outputs out of phase with inputs (IR4426) Outputs in phase with inputs (IR4427) V 6V - 20V OUT OutputA out of phase with inputA and OutputB in phase with inputB (IR4428) t (typ.) 85 & 65 ns on/off Also available LEAD-FREE Descriptions The IR4426/IR4427/IR4428 (S) is a low voltage, Packages high speed power MOSFET and IGBT driver. Pro- prietary latch immune CMOS technologies en- able ruggedized monolithic construction. Logic inputs are compatible with standard CMOS or LSTTL outputs. The output drivers feature a high pulse current buffer stage designed for mini- mum driver cross-conduction. Propagation delays between two channels are matched. 8 Lead PDIP 8 Lead SOIC Typical Connection 1 8 NC NC TO 2 7 INA OUTA LOAD IR442x 3 6 GND Vs 4 5 INB OUTB www.irf.com 1IR4426/IR4427/IR4428(S) & (PbF) ADVANCE INFORMATION Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param- eters are absolute voltages referenced to GND. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
