I'm not very familiar with mosfet motor driver but i selected mosfets depending on these parameters:
Id>10A
Vd>12
Rds<0.02
but the current appears in the n-type at the right side seems too high about -94A
another thing that i'm worried about mosfet's temp. i calculated Power desperate using this formula:
PD=Rds*I^2
then compared using the max power formula:
PDmax=(Tj-Ta)/Rja
and the result was that PD>PDmax
so i decided to use Heat sink
finaly will it be better to use "IRF1405" n-ch mosfet instead of "IRFZ44"
i want to know if this design will work or not
