2 IR2110 half h-bridge driver pin connections.įig.

I'll cover the process and will explain theory of operation. Frustrating still little information on how to operate the high voltage side MOSFET. The web is filled with the same schematic with various problems and not a clue on how it operates. The motor power supply is separate and is limited by the MOSFETs used and motor voltage up to 500-volts. I used the 15V MOSFET/IGBT gate voltage with a 5-volt regular to supply the digital voltage (VDD) of 5V. In this case the IR2110 is an 14-pin DIP IC and I used 2 for a complete h-bridge.

It does this without the use of p-channel MOSFETs or photovoltaic opto-couplers. It is designed to drive high voltage MOSFET and IGBT circuits. Note any corrections, comments, or questions email me at IR2110 is a popular h-bridge half driver.
