Description
H-b ridg e A out put
Power su pply for H-brid ge A, not co nnecte d to PV CC_ B or AVCC
Shu tdown signal for IC (low=shutd own, high=operat io nal). TTL logic
levels with complian ce to AVCC
A logic high on t his p in disables th e outp uts. A low on this pin e nables
the out puts. TTL log ic levels with co mpliance to AVCC
