LS7338 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 of SENSE or 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.
LS7338 Key Features
- Phase-Lock Loop Synchronization allows use in Wall Switch
LS7338 Applications
- Operation automatically sequences from Timed-On to Delayed-Off to Off
- On-Timer programmable with external R-C
- Transition from Timed-On to Delayed Off indicated by 31% drop in Delivered Power
- Delayed-Off period denoted by Dim-to-Off operation. (See Note 1)
