LG8150 touch step dimming light circuit

The touch mode stepper lamp of the integrated circuit, every time the finger touches M,
the brightness of the bulb E changes in cycles: low light, bright light, bright light, off, low light... This circuit is very suitable
for making adjustments. Light table lamp. r.G8] 50-end integrated circuit for touch dimming developed and produced by
    Shenzhen Luojia Haitai
Electronic Technology Co., Ltd. (ht
Lp://www. asic. net. cn). The circuit adopts CM()S technology. Manufactured with high sensitivity, high stability and island capacitive load capacity. There are various packaging forms including standard DIP-8 and soP-8 before H. The pure pin functions are: ① Pin CK, which is the system frequency input terminal; ② Pin Fl, which is 5. Hz frequency input terminal; ③ pin V... is the positive terminal of the power supply, ④ pin TI is the touch sensing input terminal; ⑤ pin (:1, is the sensor control terminal; ⑥ pin NC, is the empty pin; ⑦ pin Vss, the negative terminal of the power supply ; ⑧ pin AT is the trigger pulse input terminal to drive the thyristor. I. (, 81 50 typical 1 makes the voltage 6 SV.     In the middle, the ruler, VD, vs and ■ form a power circuit, outputting 6 8V DC The voltage supplies power to IC;8150 . C. and C are connected in series with two high-voltage CBB capacitors to improve the safety of the circuit .
