SMD SGL8023W (3.9mm Width) SOIC-08

Single-channel dual output DC LED lighting control touch-chip

SGL8023W is a single-channel touch chip for LED light brightness adjustment and switch control. Use this chip to achieveTouch switch control and brightness adjustment of LED lights. It has the following features and advantages:One touch input can control two LED outputs.The brightness of the light can be adjusted at will according to the needs, with a wide selection range and simple and convenient operation.The touch function can be realized under the isolation protection of media (such as glass, acrylic, plastic, ceramic, etc.) with high security.The application voltage range is wide, and it can be arbitrarily selected between 2.4~5.5V .The application circuit is simple, the peripheral devices are few, the processing is convenient, and the cost is low.Good anti-power interference and mobile phone interference characteristics. EFT can reach more than ± 2KV ; in the case of short-distance, multi-angle mobile phone interference,Touch response sensitivity and reliability are not affected.


FeaturesAt initial power-on, the two outputs LO1 and LO2 are off.When touch is clicked (the touch duration is less than 550ms ), the light switch and output switching function can be realized. The first touch,LO1 is on; the second time you click the touch, LO1 is off, and LO2 is on; the third time you click the touch, LO2 is off. So cycle. AnytimeAt most, only one output is on, or both outputs are not on. It is impossible for both outputs to be on at the same time. The initial brightness of each light is fixedSet as the highest brightness, no brightness memory function.When there is a light on, long press the touch (touch duration is greater than 550ms ), it can realize the current lighting of the lightStepless brightness adjustment of the light. Long press the touch once, the brightness of the light gradually increases, and the brightness of the light stops at the corresponding moment when it is released.Brightness, if the long press time exceeds 3 seconds, the light brightness will not change after reaching the maximum brightness; long press the touch again, the lightThe brightness gradually decreases. When the release is released, the brightness of the light stops at the corresponding brightness at the moment of release. If the long press time exceeds 3 seconds, the light is onAfter reaching the minimum brightness, it will not change. So cycle.If the two lights are not on, long press the touch, then LO1 will light up at the lowest brightness first, if the long press is not released, it will light upThe degree of brightness gradually increases to start stepless dimming, and does not change until the touch is released or the maximum brightness is reached.Tap to touch and long-press to touch can be used at any time without interference and restriction of mutual functions.
