Product Summary

The LS7232 is a monolithic, MOS integrated circuit designed for the control of brightness of incandescent lamps. The outputs of these ICs control the brightness of a lamp by controlling the firing angle of a triac connected in series with the lamp. All internal timings are synchronized with the line frequency by means of a built-in phase-lock loop circuit. The output occurs once every half-cycle of the line frequency. Within the halfcycle, the LS7232 output can be positioned anywhere between 158°conduction angle for maximum brightness and 41 conduction angle for minimum brightness in relation to the AC line frequency. The positioning of the output is controlled by applying a low level at the SENS input or a high level at the EXT input.

Parametrics

LS7232 absolute maximum ratings: (1)DC Supply Voltage VSS: +20 V; (2)Any Input Voltage VIN: VSS -20 to VSS + 0.5 V; (3)Operating Temperature TA: 0 to +80 ℃; (4)Storage Temperature TSTG: -65 to +150 ℃.

Features

LS7232 features: (1)Phase-lock loop synchronization allows use in Wall Switch applications; (2)Provides brightness control of incandescent lamps with touch plates or mechanical switches; (3)Controls the duty cycle from 23% to 88%; (conduction angles for AC half-cycles between 41 and 158 respectively.); (4)Operates at 50Hz/60Hz line frequency; (5)Extension input for remote activation.; (6)Input for slow dimming.; (7)+12V to +18V DC Power Supply voltage. (VSS - VDD).
