Abstract: Embodiments described herein include a method for reducing power consumption in a capacitive touch sensor. The method includes driving the capacitive touch sensor with an operating voltage at a first voltage level. The method also includes entering the capacitive touch sensor into a sleep mode responsive to a lack of touch input to the capacitive touch sensor. The method includes reducing the operating voltage to a second voltage level, and driving the capacitive touch sensor with the operating voltage at the second voltage level.
