FIGURE 6. Application Circuit For Touch Control Operation

TO SENS, PIN 5

The Application Circuit shown in Figure 6 can be applied to the Reverse Dimmer cir-

cuits shown in Figure 4 (Option 1) and Figure 5 (Option 2). The Touch Output is con-

nected to the SENSE input (Pin 5) of LS7636. When using the circuit shown in Figure

6, the following components must be removed in Figure 4 and Figure 5:

Figure 4 - Remove R6, D5, EXT SWITCH and SENSE SWITCH. C3 remains.

Figure 5 - Remove R5, D3, EXT SWITCH and SENSE SWITCH. C3 remains.
