DESCRIPTION:

The LS7317 is a MOS circuit for controlling the speed of an AC motor. Five inputs, PL1/ through PL5/ are provided to select five speed/power levels between 40% and 96% of full power. A BOOST/ input is provided to override any selected power level with a jump to 99% of full power.

FEATURES:

•Inputs/Outputs for selecting and displaying 5 speed/power levels Electronically latched inputs with dome switch compatibility

•Separate Boost input for full-speed/power selection

•Separate Pulse input for periodic on/off cycle selection

•+6V Operation (VDD- VSS)

• LS7317 (DIP); LS7317-S (SOIC) -See Figure 1-



Applications:

• Consumer Appliances such as Blenders, Range Hoods, Fans, etc.

• Lamp Dimmer for control of high-voltage lamps and electronic-transformer coupled low-voltage lamps such as Halogen Lamps.
