本文介绍一种新颖多功能调光灯控集成电路GY7706,它具有无级、有级调光和延迟关灯及循环自动开关灯等四种不同功能。CY7706是CMOS大规模集成电路,(16)脚双列直插塑封包装,图1是它的管脚图。各管脚功能如下; ①脚Z、C,交流电过零信号输入端;②脚OSC1,振荡器输入端;③脚OSC2,振荡器输出瑞;④脚TEST,测试端,平时可悬空;⑤脚T1,测试端,平时悬空;⑥脚OUT,控制信号输出端,控制信号经电容C2加到可控硅VS的门极G,以控制VS
This article introduces a novel multi-function dimming light control integrated circuit GY7706, it has a stepless, step-level dimming and delay off the light and cycle automatically turn on and off lights, and other four different functions. CY7706 CMOS large scale integrated circuits, (16) dual in-line plastic package, Figure 1 is its pin diagram. The function of each pin is as follows: ① feet Z, C, AC zero crossing signal input; ② feet OSC1, oscillator input; ③ feet OSC2, the oscillator output Swiss; ④ feet TEST, test side, T1, the test terminal, usually dangling; ⑥ foot OUT, the control signal output, the control signal is added to the gate of the thyristor VS G by the capacitor C2 to control the VS
