I don't understand how you charge the bootstrap capacitor if u only use the high side mosfet... Through the motor? If u only have one mosfet, then use the low side. Connect HIN to GND.now i connect the ir2110 and used a 4ohm 2w gate resistance but when working @ frequency 144 hz no problem and when working on 2300hz or 14400 hz the ic get hot
i use this conf. but @ 9 i connect 12v +
edit: i did use only one mosfet the high one only it run the small motor but the ic is getting hot
Try to use a bigger value for the gate resistance.
What did you connect at Vb and Vcc? Is the circuit u posted exactly what u built except for the low side mosfet which u said u didn't use?
