Title:
VOLTAGE SUPPLY CONTROL CIRCUIT AND OPERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/167155
Kind Code:
A1
Abstract:
Provided is a voltage supply control circuit capable of making a circuit unit perform stable operations by supplying a power generation voltage supplied from a power generation unit by controlling the power generation voltage such that the power generation voltage conforms to a power supply voltage specified by the circuit unit. In the case where the power generation voltage V3 of the power generation unit 3 is equal to or lower than a first voltage Vth1 during a time when the power generation unit 3 is operated by being pressed, and the power generation voltage V3 of an input terminal 13 is increasing, voltage supply from the power generation unit 3 to a transmission unit 5 is stopped. In the case where the power generation voltage V3 exceeds the first voltage Vth1, an output voltage V3' is supplied to the transmission unit 5. In the case where the power generation voltage V3' becomes equal to or lower than a second voltage Vth2 that is lower than the first voltage Vth1, voltage supply from the power generation unit 3 to the transmission unit 5 is stopped.
