AN603:
Operating ICON H-Bridges in Parallel
1
Overview:
There may be instances where the 12A continuous current handling capability of the ICON HBridge is not adequate for a specific application. For higher current applications there are at least two options that can be implemented to allow the ICON H-Bridge to meet the needs of the design. The first option is to increase the power dissipating capability of your system. This can most easily be accomplished by increasing the forced airflow over the ICON H-Bridge with a highspeed, high-volume, fan. But even with increased airflow the ICON H-Bridge will probably not be capable of continuously handling more than 20A of continuous current due to the size of the ICON H-Bridge PCB.
