IR2104 Description

The IR2104 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 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 from 10 to 600 volts.

Frequently Asked Questions

How does IR2104 work?
The IC IR2104 is a half-bridge MOSFET gate driver. It drives the high and the low side MOSFETs using the PWM signal from the Arduino (Pin -D9). The IR2104 can also be shut down with the control signal (low on the pin -D8) from the Arduino on pin 3. It caps the PWM duty cycle at 99.9% to keep the charge pump working.
What is a half bridge gate driver?
The isolated half-bridge driver's function is to drive the gates of high- and low-side N-channel MOSFETs (or IGBTs) with a low output impedance to reduce the conduction losses, and a fast switching time to reduce the switching losses.
What is the difference between half bridge and full bridge inverter?
The main difference between the two configurations is that the output voltage of the full-bridge inverter is equal to the power supply voltage while the output voltage for the half-bridge inverter is equal one half of the power supply voltage.
