Features Floating channel designed for bootstrap operation Fully operational to +6V Tolerant to negative transient voltage dv/dt immune Gate drive supply range from to 2V Undervoltage lockout V Schmitt-triggered input logic Cross-conduction prevention logic Internally set deadtime High side output in phase with input Match propagation delay for both channels Description The IR2 is a high voltage, high speed power MOSFET and IGBT driver with dependent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL outputs. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration which operates from to 6 volts.
