LS7338 General Description
The LS7338 is a monolithic MOS integrated circuit designed to turn a triac On and Off in a Power Switch for Incandescent Lighting. Activation ofSENSEor SLAVE inputs turns the triac On and starts a timer. The triac remains On for the duration of the Timer which is controlled by an external R-C connected to the OSCILLATOR input.
When Time-out occurs, the power delivered by the triac is stepped down by 31% and then slowly reduced to Off over a fixed period of time.
In a typical application (Figure 5), the output of the LS7338 drives the gate of a triac in series with the load.
There are three states through which the LS7338 can be stepped.
The states and their corresponding operating mode, phase angles and delivered power levels are shown in Table 1.
