典型应用电路图
概述
是一款双通道电容式的触摸
台灯控制芯片，可用单键触摸来控制两路
输出。
应用电路简单，外围仅需两
个电容和一个电阻就可以实现触摸控制功
能，加工方便、成本低，并且采用电容式
检测方式可实现触摸开关与控制电路相隔
离，安全可靠。
不仅具有简单的开启或关闭
触摸开关控制功能，还具有无极调光的控
制模式，
可实现占空比 0%到 100%的调光。
自带一定的负载输出能力，
也可以使用外置的 NPN 或者 NMOS 实现
扩流。
还可以与
、
和
结合使用来实现 LED 的恒流驱
动。
采用 SOP8 封装。
特点
 电源电压：3.0V~6.0V
 工作模式：单键触摸控制两通道
 无极调光：占空比 0%～100%
 内置上电复位
 自带负载输出能力：
IOUT =100mA @6.0V
IOUT =77mA @5.0V
IOUT =43mA @4.0V
应用领域
 触摸调光台灯
 便携式照明设备
