 04 Jul 2006 21:13 DC motor control with IR2110 |

I have to build a device that controls the speed of a DC motor 127V,10A. I decided to use IR2110 - half bridge MOSFET driver and IRFP260N - N-channel MOSFET. And here the problems begin.
When I apply 1kHz (50% duty cycle) pulses to LIN and HIN from PIC there is no response on LO and HO. I tried another test - I just applied 5V to LIN expecting to get 15V but there was 0V.
I apply 30V to high side mosfet, because I can't provide 127V but I don't think this is a problem.
So is there any wrong with the circuit?
How can I test the IR2110 to see if it is broken?
Any practical applications of IR2110 are welcome.
