SX8010 Single channel DC LED Light Control Touch ChipDetailed product description：

1. Overview
SX8010 single channel DC LED light control touch chip is a single channel touch chip used for LED light brightness adjustment and switch control. This chip can be used to achieve touch switch control and brightness adjustment of LED lights. It has the following functional characteristics and advantages:
The brightness of the lights can be adjusted as needed, with a wide selection range and simple and convenient operation.  
Touch function can be achieved with isolation and protection from media such as glass, acrylic, plastic, ceramics, etc., ensuring high safety.  
The application voltage range is wide, and can be freely selected between 2.4~5.5V.  
The application circuit is simple, with few peripheral components, easy processing, and low cost.  
Good resistance to power interference and mobile phone interference. EFT can reach ± 2KV or above; In the case of close range and multi angle mobile phone interference,
The sensitivity and reliability of touch response are not affected.  

Characteristics
TI touch input corresponds to SO light control output. There are four functions to choose from, determined by the input status of OPT1 and OPT2 pins before power on. as follows:
1) OPT1=1, OPT2=1 corresponds to: LED touch stepless dimming function without brightness memory for sudden brightness changes
2) OPT1=0, OPT2=1 corresponds to: LED touch stepless dimming function without brightness memory gradually increasing and decreasing
3) OPT1=1, OPT2=0 corresponds to: LED touch dimming function with brightness memory that gradually brightens and dims
4) OPT1=0, OPT2=0 corresponds to LED three-stage touch dimming function
The LED touch stepless dimming function without brightness memory is as follows:
1) When initially powered on, the light is in the off state.
2) When the touch is clicked (with a duration of less than 550ms), the light can be controlled to turn on or off. One click touch, the light will turn on; Click touch again and the light will turn off. Such a cycle. When the light is turned on or off, there is no brightness buffer. And the initial brightness of the lighting is fixed at 50% of the full brightness.
3) Long press touch (touch duration greater than 550ms) can achieve stepless brightness adjustment of the light. Long press and touch once, the brightness of the light gradually increases. When released, the brightness of the light stops at the corresponding brightness at the time of release. If the long press time exceeds 3 seconds, the brightness of the light will reach its maximum brightness and will no longer change; Press and hold the touch again, and the brightness of the light gradually decreases. When released, the brightness of the light stops at the corresponding brightness at the time of release. If the press and hold time exceeds 3 seconds, the brightness of the light will reach its minimum brightness and will no longer change. Such a cycle.
4) Click touch and long press touch can be used at any time without interference or limitation in their functions.  
The LED touch stepless dimming function without brightness memory gradually brightens and dims is based on the LED touch stepless dimming function without brightness memory suddenly brightens and dims. When clicking the touch to turn on and off the light, the light slowly and smoothly transitions from a lower brightness to the initial brightness when turned on. When clicking the touch to turn off the light, the light slowly and smoothly decreases from the current brightness until it is turned off, thus achieving a visual buffering effect of slow brightness changes and protecting the eyes and vision.  
The LED touch stepless dimming function with brightness memory gradually brightens and dims adds brightness memory function on the basis of the LED touch stepless dimming function without brightness memory gradually brightens and dims. When the AC220V power supply is not powered on, the brightness at each touch to turn off the light will be remembered, and the next touch to turn on the light will use this brightness as the initial brightness. When the AC220V power supply loses power, the first touch to turn on the light after powering it back on will fix the initial brightness at 50% of the full brightness.  
LED three-stage touch dimming function
1) When initially powered on, the light is in the off state.
2) Each time you click on the touch, the brightness of the light will cycle in the order of low brightness ->medium brightness ->high brightness ->off.
