Figure 3. Timing diagram
10, 16 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.
11, 15 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).
12, 14 RC
A parallel RC network connected to this pin sets the OFF
time of the higher power transistors. The pulse generator is
a monostable triggered by the output of the comparators
(t
off
= 1.1 RT CT).
