| Data Sheet No. PD60177 Rev. E IR4426/IR4427/IR4428(S) & (PbF) DUAL LOW SIDE DRIVER Features * Gate drive supply range from 6 to 20V * CMOS Schmitt-triggered inputs * Matched propagation delay for both channels * Outputs out of phase with inputs (IR4426) * Outputs in phase with inputs (IR4427) * OutputA out of phase with inputA and * Also available LEAD-FREE OutputB in phase with inputB (IR4428) Product Summary IO+/VOUT ton/off (typ.) 1.5A / 1.5A 6V - 20V 85 & 65 ns Descriptions The IR4426/IR4427/IR4428 (S) is a low voltage, high speed power MOSFET and IGBT driver. Proprietary latch immune CMOS technologies enable 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 minimum driver cross-conduction. Propagation delays between two channels are matched.
