SX8653IWLTRT

The input supply range for the SX8653 touch controller is from 1.65V to 3.7V.

The low power modes in the SX8653 touch controller are designed to preserve current when the screen is unintentionally touched, allowing for power conservation. These modes also enable the activation of a low power 12-bit analog-digital converter with on-chip data averaging processing algorithms to reduce host activity and suppress system noise, ensuring precise computation of touch screen X-Y coordinates and touch pressure. Additionally, the touch screen controller inputs provide robust on-chip ESD protection of up to ±15kV in both HBM and Contact Discharge, eliminating the need for external protection devices.

The multitouch feature of the SX8653 touch controller supports gestures such as the Zoom Gesture and Rotate Gesture. The Zoom Gesture involves a thumb and forefinger "pinch" movement to enlarge or make objects smaller onscreen. On the other hand, the Rotate Gesture allows users to rotate objects onscreen by making clockwise or counterclockwise movements with the anchored thumb and forefinger. These gestures enable swift and accurate positioning of objects without the need for repeated pointing and clicking.
