2 / 4 page The differences among all versions of LS7634 and LS7635 are: LS7634 (LS7634FO) Upon power-up, the TRIG output is Off. (Upon power-up, the TRIG output is On at maximum conduction angle.) When a LONG touch is applied, the dimming direction automatically re- verses whenever maximum or minimum conduction angles are reached. LS7635 (LS7635FO) Upon power-up, the TRIG output is Off. (Upon power-up, the TRIG output is On at maximum conduction angle.) When a LONG touch is applied, the dimming stops whenever 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. TABLE 1 MODE SHORT TOUCH LONG TOUCH DIMMING REVERSAL PRE-TOUCH Ø POST-TOUCH Ø PRE-TOUCH Ø POST-TOUCH Ø (Note 5) OFF MAX(Note 1) OFF/MIN Varies up from MIN N/A 0 ON OFF MAX Varies down from MAX N/A INTERMEDIATE Varies from INTERMEDIATE NO OFF MEMORY OFF Varies from memory (Notes 2, 3,4) YES 1 (Notes 2, 3) MIN Varies up from MIN N/A ON OFF MAX Varies down from MAX N/A INTERMEDIATE Varies from INTERMEDIATE YES OFF MAX (Note 1) OFF/MIN Varies up from MIN N/A 2 ON OFF MAX Varies down from MAX N/A INTERMEDIATE Varies from INTERMEDIATE YES Note 1: A soft turn-on is produced by slewing up the conduction angle, ø, from minimum at the rate of 1.4 ˚/8.33ms (60Hz). Note 2: A soft turn-on is produced by slewing up ø, from minimum to memory. Upon power-up the memory value is defaulted to maximum conduction angle. Note 3: “Memory” refers to the conduction angle, ø, which existed prior to the current off-state. Note 4: A soft turn-on is produced by slewing up ø 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. 7634/7635-010906-2 LS7635 NOTE: If the User applies a LONG Touch when the TRIG Conduc- tion Angle is within a “few” degrees of Maximum or Mini- mum, the TRIG Conduction Angle can move to Maximum or Minimum and stop without the User being able to observe a change in brightness. There-fore, the User should be in- structed that if no change in brightness is observed in re- sponse to a LONG Touch, the LONG Touch should be re moved and reapplied in order to produce a change in bright- ness.
