Semtech offers ultra-low power 4-wire and 5-wire resistive touchscreen controllers optimized for portable equipment where power and board-space are at a premium. Our ultra low power, fully integrated touchscreen controller platform enables multi-touch gestures on regular 4-wire resistive touchscreens and supports proximity on any panel. It also features advanced haptics control as well as robust on-chip ESD protection in a small footprint.
In addition, our fully integrated, haptics enabled 4D-Touch family of resistive touchscreen controllers (SX8654/55/56/57/58) feature a unique built-in proximity sensing circuitry which enables proximity detection in applications where automatic system wake up or backlight LED dimming adjustments are required without the need for any additional components. The SX865x family can directly connect to an ERM or LRA Motor to create haptic feedback, thus eliminating the need for a dedicated I2C interface. Features
