Hello experts! I am starting to build a H-bridge motor controller using 2xIR2110 driving 4xIRF3205. I am using PIC 18F1320 using ECCP module to generate the inputs to the two IR2110. There are 4 outputs with ECCP, only 1 input is pulsed (I will connect this to HIN on IR2110#1) and the diagonally opposite output is always high (I will connect to LIN on IR2110#2). The other 2 diagonal outputs are low. To reverse the direction, it simply uses the other diagonal outputs.
Will this work with IR2110? I think this will effective charge the boost capacitor through the motor winding. Or do I need to pulse LIN as well (by not using the 2 outputs from ECCP and just inverting HIN on the same IR2110)?
