The TTP223E-BA6 is a SOT-23-6 RoHS-compliant touch screen controller IC manufactured by Tontek. The IC is used to control touch panels in embedded systems such as mobile phones, PDAs, and other personal devices. It has a detection threshold of ˜6 N and can detect any object, including finger, stylus, stylus pen, and other conductive objects. The IC also features low-power operation and advanced immunity against external noise noise. It also integrates a debounce timer to reduce false detection. The IC consumes a maximum power of 10µA while in detect mode and 5µA while in sleep mode, making it an ideal choice for battery-powered applications.
