The functional differences between LS7631 and LS7632 are:
LS7631
- When a LONG touch is applied, the dimming direction auto-
matically reverses whenever maximum or minimum conduction an-
gles are reached.
LS7632
- When a LONG touch is applied, the dimming stops when-
ever maximum or minimum conduction angles are reached. In order to
change dimming levels from maximum or minimum, LONG touch must
be removed and reapplied.The purpose of this feature is to allow the
user to positively locate maximum and minimum conduction angles.

Note 1
:
A soft turn-on is produced by slewing up the conduction angle, , from minimum at the rate of 1.4
/4.17ms (60Hz).
There are a total of 84 discrete values of .
Note 2
: A soft turn-on is produced by slewing up , from minimum to memory.
Upon power-up the memory value is defaulted to maximum conduction angle.
Note 3
:
“Memory” refers to the conduction angle, , which existed prior to the current off-state.
Note 4
: A soft turn-on is produced by slewing up from minimum to memory upon which the dimming is started.
Note 5: NO
= Dimming direction does not reverse from prior dimming direction.
YES
= Dimming direction does reverse from prior dimming direction.
N/A
= Does not apply.

LS7632 NOTE
: If the User applies a LONG Touch when
the TRIG Conduction Angle is within a “few” degrees of
Maximum or Minimum, the TRIG Conduction Angle can
move to Maximum or Minimum and stop without the User
being able to observe a change in brightness. Therefore,
the User should be instructed that if no change in bright-
ness is observed in response to a LONG Touch, the
LONG Touch should be removed and reapplied in order
to produce a change in brightness.
