Abstract: A power management apparatus and a power management method are provided. The method includes the following steps. Conduct a first current path during a first period. Provide a first voltage to an operation end when the first current path conducts and a microprocessor is disabled. The first voltage is used to selectively conduct a second path during the first period. Provide a second voltage to the microprocessor when the second current path conducts. The second voltage is used to turn on the microprocessor. Provide a third voltage to the operation end by the microprocessor when the microprocessor is turned on. The third voltage is used to keep the second current path conducted.

Abstract: A touch input device provided in the present invention includes a pen tip, a pressure sensing module, a control unit and a PWM generator. The pen tip is utilized to touch a capacitive touchscreen and conduct a touchscreen driving signal. The pressure sensing module is utilized to generate a pressure sensing signal which corresponds to a pressure of the pen tip on the capacitive touchscreen. The control unit is utilized to receive the touchscreen driving signal and the pressure sensing signal, and then to generate a PWM control signal according to the pressure sensing signal. Further, a pulse width of the PWM control signal is proportional to the pressure. The PWM generator is utilized to provide a PWM signal to the pen tip according to the PWM control signal. A touch input system is further provided in the present invention.
