IR2184(4)(S) & (PbF)
Features
• Floating channel designed for bootstrap operation
Fully operational to +600V
Tolerant to negative transient voltage
dV/dt immune
• Gate drive supply range from 10 to 20V
• Undervoltage lockout for both channels
• 3.3V and 5V input logic compatible
• Matched propagation delay for both channels
• Logic and power ground +/- 5V offset.
• Lower di/dt gate driver for better noise immunity
• Output source/sink current capability 1.4A/1.8A
• Also available LEAD-FREE (PbF)

CMOS or LSTTL output, down to 3.3V
logic. 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 up to 600
volts.
