Product Introduction
Capacitive Touch Chip - GTX315L is GreenTouch 3LPTMOne of the capacitive touch sensor series products. In particular, GTX315L can perform capacitive detection with 15 channels under GreenTouch 3LPTMEngine running. Due to GreenTouch 3LPTMLow-power engine, various battery-powered applications can increase product usage time. Also based on existing GreenTouch3TM engine technology, reliability can be guaranteed against various noise and environmental changes. Internal control registers can be read/written via I2C interface. GTX315L can be applied to a wide supply voltage range of 1.8V to 5.5V. The CTRL pin of GTX315L provides switchable chip ID for two-chip parallel operation on the same I2C bus.
