Hi,
As a newbie to h-bridge I am a little confused about the options for choosing a MOSFET H-bridge gate drivers for a 24v DC motor(about 10A). It appears that a simple way to drive the H-bridge is to turn on the high side which then can trigger the low side as in Eugene Blanchard's design here H-bridge using P and N channel FETs - The Using MOSFETS Website (note that the label there probably should have been "N channel MOSFET" instead of P and N). Also, there are probably other ways to provide the high voltage needed for the high side, as well as using opto switches. In any case, the point is that all is needed in his design is to turn on the high side and trigger the low side. I like the simplicity in this design and it sounds great. But somehow, the figure is labeled as "Obsolete". Does anyone know why?
I understand that there are special chips such as IR2110, or HIP48xx series but can someone comment on what additional benefits these chips offer compared to Eugene's design? Does his design have a high probability of shoot through (don't know how deadtime is handled here)? Also, any comments on the choice between IR2110 and HIP48xx series would be appreciated. Thanks.
