TTP223-BA6 One-Touch Key Detecting 6-Pin IC (SOT23) Pack of 3000

The TTP223-BA6 is a high-sensitivity, touch-sensing IC designed for capacitive one-touch key detection. Packaged in a compact SOT23-6 form factor, this chip offers a simple, low-power solution for replacing traditional mechanical buttons with modern touch interfaces. Ideal for touch switch applications, the TTP223-BA6 detects changes in capacitance when a finger is placed near a touch pad, and outputs a stable digital signal that can be directly interfaced with microcontrollers, relays, or logic circuits. This IC features automatic calibration, low standby power consumption, and configurable modes including momentary or toggle output. It operates over a wide voltage range of 2.0V to 5.5V, making it compatible with both 3.3V and 5V logic systems. Built-in debounce functionality ensures clean, stable touch detection, and its small size allows for integration into space-constrained designs. Whether you're designing smart lighting systems, touch-enabled panels, or custom embedded projects, the TTP223-BA6 delivers reliability, ease of use, and solid performance in capacitive touch applications. It's an ideal choice for DIY electronics, consumer gadgets, and IoT devices where touch-based input is desired.
