plug-in (AC Hot and Neutral) dimmer configurations

 
Multi-Level Dimmer…. (14 Pins)
LS7317, LS7317-S
Last Update: 01/26/09
Pushbutton input controls
Up to 5 selectable intensity (power) levels
A selected intensity level input becomes an output  
that can drive a LED to indicate the selected intensity
Controls high-voltage lamps and electronic-transformer
coupled low-voltage lamps via a triac interface

Applications include wall switch (AC Hot) and
plug-in (AC Hot and Neutral) dimmer configurations

 
Light Dimmer with Up and Down Controls…. (8 Pins)
LS7535FT, LS7535FT-S
Last Update: 11/11/09
Touch or pushbutton UP and DOWN input controls
Momentary UP/DOWN input activation causes instant return to MEMORY ON / OFF state
Prolonged UP/DOWN input activation cause variable dimming
operation towards MAX/MIN Brightness Levels
DOZE input for external control of DIM-TO-OFF time
 
AGC Touch Control Step Dimmer…. (8 Pins)


LS7538, LS7538-S; LS7539, LS7539-S
Last Update: 01/27/03
LS7541, LS7541-S
Last Update: 03/23/07
Touch Sensitivity is independent of Touch Plate Size and Line-Plug Polarity
Pin selection of three available Brightness Step Sequences
LS7539 and LS7541 are functionally equivalent
Pushbutton control can be used instead of 'Touch'.
Applications include Wall Switch step dimmers and Touch Control step dimmers for small table lamps to large floor lamps.
 
AGC Touch Control Light Switch with Soft-Off …. (8 Pins)
LS7540, LS7540-S
Last Update: 11/06/07
Touch Sensitivity is independent of Touch Plate Size and Line-Plug Polarity
If Off, a 'Touch' produces Max Intensity (On) instantaneously
If On, a 'Touch' initiates intensity ramp-down (Soft-Off). Max intensity to Off ramp-down time is programmable by an external RC. The Soft-Off feature provides light for the User to exit the room. Ramp-down time = 0 if no RC is connected.
Application of a 'Touch' during ramp-down causes the ramp-down to stop. Once stopped, a 'Touch' causes the ramp-down to Off to resume. Stopping and starting the ramp-down can be repeated as often as desired thus giving the User full control in setting the light intensity.
Pushbutton control can be used instead of 'Touch'.
Applications include Wall Switches and Touch Control modules for small table lamps to large floor lamps
