FIGURE 4. LS7635 TRIG, vs TOUCH (SENS OR EXT)
EXTENSIONS:
All switching and dimming functions can be
implemented by utilizing the EXT input. Use a pushbutton or
the electronic switch in conjunction with a Touch Plate as
shown in Figure 6. When the plate is touched, a logic high
level is generated at the EXT input of the IC for both half-
cycles of the line frequency. (See Figure 5)
APPLICATION EXAMPLE:
A typical implementation of the light dimmer circuit is shown in Fig. 5.
Here the brightness of the lamp is set by touching the touch plate.
The function of different components are as follows:
The 5V DC supply for the chip is provided by Z, D1, R1, C2 and C4.
R2 and C3 generate the filtered signal for the SYNC input
AC phase synchronization.
R3 and C5 act as a filter circuit for the electronic extension.
If extensions are not used, the EXT input (Pin 6) should be
tied to Vss (Pin 7).
R4, R5 and R6 set up the sensitivity of the SENS input.
R8 provides current limiting and isolation between the chip
output and the triac gate.
C1 and L are RFI filter circuits.

NOTES
1.
All circuits connected by broken lines are optional.
2.
C5 is used only with electronic extension
and R7 is used only with mechanical switch.
3.
Connection between Pin 6 & Pin 7 should
be broken when EXT is used.
4.
Magnetic transformer should have thermal protection.
5.
Some electronic transformers may require larger
values of C2, sensitive gate triacs and snubber
networks. C2 values may have to be adjusted to be as
high as 0.47uF for 115VAC and 0.33uF for 220VAC.
The sensitive gate triacs are chosen for their low
holding current. Typical triacs are L400

**C6-R9 is the snubber network: C6 = 0.1uF, 200V,
R9 = 1k Ohm, 1/2W (115VAC); C6 = 0.05uF, 400V,
R9 = 1k Ohm, 1W (220VAC)
