触摸按键处理芯片

FTC627B是专业的电容式触摸按键加数码管驱动芯片，采用最新高精度数字电容测量技术，能做到防各种干扰、防面板水珠影响、适应各种电源供电等。能支持到7个触摸按键,48个LED驱动。通讯接口采用市面上通用的1628通讯模式，只需要3根线。非常适用各种带数码屏的电器产品的应用。 • 超强抗EMC干扰，能防止功率大到5W的对讲机等发射设备天线靠近触摸点干扰。\n• 极简单外围电路，最简单的应用外围只需要一颗参考电容。（视客户要求如需要提高ESD和EMC则需每个按键接1颗电阻）\n• 防水淹干扰，成片水珠覆盖在触摸面板上不影响按键的有效识别。\n• 超宽工作电压范围3.0V—5.5V ，能应用在目前广泛应用的3.3V系统和3.0V电池系统。\n• 电源电压变化适应功能，内置电压补偿电路，电源电压在工作范围内变化时自动补偿，不影响芯片正常工作。\n• 环境温度湿度变化自动适应，环境缓慢适应技术的应用，使得芯片无限长时间连续工作不会出现灵敏度差异。\n• 可调灵敏度，可以通过;
