Touch dimming IC
CT8022
CT8022 is a light control IC specially designed for LED table lamps, which can detect all the lights by single touch, and realize ON/OFF and none by touching the keys.
Level dimming or segment dimming control. The touch function can be realized under the condition of isolation and protection of media (plastic shell, glass ceramics, acrylic, etc.).
High security. A variety of working modes are configured through external pins, with brightness power-off memory and ON/OFF on-off visual angle buffer to protect eyes and eyesight.
The effect.
