DESCRIPTION:

The LS7310-LS7313 are MOS integrated circuits specifically designed for motor speed control applications in appliances such as blenders, etc. I/Os (PLs) are provided for selecting/indicating from one to ten power levels. The LS7310 and 7311 are designed for pushbutton control. The LS7312 and LS7313 are designed for touch control. (See Fig.4A and 4B)

FEATURES:

• 10 I/Os to Select/Indicate up to ten Power Levels

• Inputs activated by Touch or Pushbutton Switch

• Output switches pure and precise AC Power to Load

• Operates with 50Hz/60Hz line frequency

• Rugged, latchup-free process technology

• +10V to +14V operation (Vss-VDD)

• LS7310 thru LS7313 (DIP);

LS7310-S thru LS7313-S (SOIC) - See Figure 1

APPLICATIONS:

Universal and shaded-pole motor speed control for modern

appliance designs. Eliminates awkward mechanical switch

assemblies and multi-tapped motor windings.
