A: The FT3519 is a capacitive touch chip.
The capacitive touch chip integrates a high-resolution touch detection module and a special signal processing circuit to ensure that the capacitive touch chip has a sensitive automatic recognition and tracking function to environmental changes. Capacitive touch chips must also meet the high experience requirements of users in complex applications in terms of stability, sensitivity, power consumption, response speed, water resistance, water operation, vibration resistance, and electromagnetic interference resistance.
