FTC334C

Capacitive touch IC key processing chip FTC334C 

Features

Super anti-EMC interference

can prevent interference from the antennas of transmitting equipment such as walkie-talkies with power up to 5W close to the touch point.

Extremely simple peripheral circuit, the simplest application peripheral only requires a reference capacitor.

Waterproof and flood-resistant, and sheets of water droplets covering the touch panel will not affect the effective identification of the buttons.

Ultra-wide operating voltage range 3.0V-5.5V, can be used in 3.3V systems and 3.0V battery systems that are currently widely used.

Power supply voltage change adaptation function, built-in voltage compensation circuit, automatic compensation when the power supply voltage changes within the working range, without affecting the normal operation of the chip.
