IR2181 Description
The IR2181 is a high voltage high-speed power MOSFET and IGBT driver with independent 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 output, down to 3.3V logic. The output driver IR2181 features 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 600V.
IR2181 Features
Floating channel designed for bootstrap operation
Tolerant to negative transient voltage (dV/dt immune)
Under-voltage lockout for both channels
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 1.4/1.8A
IR2181 Applications
Robotics
Home appliances
Motor control and drives
Power tools
Power Supplies
Home and building automation
Industrial heating and welding
Uninterruptible power supply (UPS)
