TTP223-BA6 SMD IC TOUCH SENSOR SOT23-6 TONTEK TTP223-BA6

Product Overview

These ICs provide a reliable, wear-free method for 1-key touch detection. They are designed to be easily integrated into systems requiring a modern interface, offering both high sensitivity and stability. Because they lack moving parts, they provide significant advantages in longevity and aesthetics compared to standard mechanical buttons.

Core Specifications

• Manufacturer: TONTEK

• Package Type: SOT-23-6L

• Function: 1-Key Touch Pad Detector

• Operating Voltage: 2.0V to 5.5V

• Output Type: CMOS output (configurable as active high or active low)

Features

• Low Power Consumption: Includes a dedicated low-power mode with a typical current draw of 1.5µA (at 3V), making it ideal for battery-operated devices.

• Adjustable Sensitivity: The detection sensitivity can be precisely tuned using an external capacitor (range 0–50pF).

• Flexible Operation: Supports "Direct Mode" for momentary switching and "Toggle Mode" for latching behavior, both selectable via configuration pins.

• Automatic Calibration: Features an integrated auto-calibration mechanism that continuously adapts to environmental changes, ensuring long-term operational stability.

• Stable Start-up: Executes a 0.5-second stabilization period upon power-on to ensure accurate sensor initialization before accepting inputs.

Applications

• Consumer Electronics: Commonly found in smart home devices, kitchen appliances, and media players.

• Portable Gadgets: Excellent for compact, battery-powered equipment where mechanical switch space is limited.

• Control Panels: Used in domestic and industrial interface modules requiring a durable, touch-sensitive surface.

• Switch Replacement: Suitable for any application that requires a wear-free, reliable alternative to physical mechanical switches.
