DESCRIPTION:

LS7237 is a monolithic, MOS integrated circuit designed to control the brightness of an incandescent lamp.

FEATURES:

• PLL synchronization allows use as a Wall Switch

• Provides brightness control of an incandescent lamp with a touch plate or mechanical switch

• Can control speed of shaded pole and universal AC motors

• Controls the "duty cycle" from 23% to 88% (conduction angles for AC half-cycles between 45˚ and 158˚, respectively)

• Operates at 50Hz/60Hz line frequency

• Extension input for remote activation

• +12V to +18V DC Power Supply (VSS - VDD)
