LS7317 - 5-SPEED AC MOTOR CONTROLLER / 5-STEP LAMP DIMMER

General 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.

Key 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.
