Phase

This TTL-compatible logic inputs sets the direction of

current flow through the load. A high level causes current to

flow from output A (source) to output B (sink). A schmitt

trigger on this input provides good noise immunity and a

delay circuit prevents output stage short circuits during

switching

Reference voltage

A voltage applied to this pin sets the reference voltage of the

comparators, this determining the output current (also thus

depending on Rs and the two inputs input 0 and input 1)

RC

A parallel RC network connected to this pin sets the OFF

time of the higher power transistors. The pulse generator is
