Jeking Daily Post: TTP233H-HA6

#Single-Touch, #Low-Power, #Stable-Detection, #Wide-Voltage, #CMOS-Output **TTP233H-HA6 Single-Key Capacitive Touch Sensor IC** **Product Overview** The TTP233H-HA6 is a high-performance, single-button capacitive touch detection IC developed by TonTouch™, a brand under TONTEK Corporation. Designed as a modern alternative to traditional mechanical switches, this integrated circuit delivers stable and reliable touch sensing with built-in voltage regulation, ensuring consistent operation across varying environmental conditions. Its compact SOT-23 package makes it ideal for space-constrained applications, while its low power consumption supports both DC and AC power systems. **Key Features** Operating within a wide voltage range of 2.4V to 5.5V, the TTP233H-HA6 includes an internal low-dropout regulator (LDO) and built-in low-voltage reset (LVR) function for enhanced system stability. In low-power mode, it consumes only 1.5μA typical current at 3V, making it excellent for battery-powered devices. The chip offers adjustable sensitivity via an external capacitor (1–50pF), allowing customization based on application needs. It supports two output modes—direct and toggle—via the TOG pin, and output polarity can be configured through the AHLB pin. With an auto-calibration feature, the device adapts to environmental changes, ensuring long-term reliability. After power-on, a 0.5-second stabilization period ensures accurate initialization. **Typical Applications** This IC is widely used in consumer electronics such as smart home controls, LED lighting, kitchen appliances, bathroom fixtures, and wearable devices like Bluetooth headsets and fitness bands. Its waterproof and anti-interference capabilities also enable innovative uses, such as liquid level detection using metal traces or copper foil. **Supplied by Jeking Electronic Limited** Jeking Electronic Limited is a trusted supplier of electronic components, offering genuine TTP233H-HA6 ICs with full manufacturer traceability and technical support.
