Abstract
A touch sensing device and a power management method thereof are provided. The touch sensing device includes a touch panel, a power supply and a capacitor circuit. The power supply is used to provide a driving voltage to the touch panel during multiple first sub-periods of an uplink signal transmitting period, and to stop providing the driving voltage to the touch pad during multiple second sub-periods of the uplink signal transmitting period. The capacitor circuit obtains a recycle energy according to a discharge charge flowing from the touch panel during the second sub-periods of the uplink signal transmitting period.
