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
A voltage applied to this pin sets the reference voltage of the
Reference voltage comparators, this determining the output current (also thus
depending on Rs and the two inputs input 0 and input 1)
A parallel RC network connected to this pin sets the OFF
RC
time of the higher power transistors. The pulse generator is
a monostable triggered by the output of the comparators
(toff = 1.1 RT CT)
VSS - Logic supply Supply voltage input for logic circuitry
VS - Load supply Supply voltage input for the output stages
ESD on GND, VS, VSS, OUT 1 A and OUT 2 A is guaranteed up to 1.5 KV (human body
model, 1500 W, 100 pF).
