Touch sensor TTP223B (OT8822)

The TTP223B is a capacitive touch sensor that operates based on the contact of an object or person with a sensitive surface. The device is designed for use in various applications, including touch controls, touch switches and buttons, and other types of touch-activated devices. Below are the technical specifications for the TTP223B touch sensor:

Operating voltage: 2.0 V to 5.5 V DC
Detection range: 0 mm to 12 mm
Output mode: toggle mode or momentary mode (adjustable)
Output voltage: equal to the power supply voltage (Vcc) in momentary mode; high or low at toggle mode (adjustable)
Output current: 500mA (maximum)
Operating temperature: -20°C to +70°C

The TTP223B touch sensor has a built-in debounce circuit to prevent interference and has a low current consumption of less than 1mA in standby mode. The sensor has a fast response time of less than 60ms and has a long lifespan of over 100,000 cycles.
