The purpose of the present invention is to provide a battery-type power supply device with a current detection function, said battery-type power supply device being provided with a wireless communication function. A battery-type power supply device of the present invention has a housing having a shape and dimensions conforming to battery standards so that the battery-type power supply device can be mounted in a battery box of an external load device. A battery housing unit 2 for housing an external battery in the housing has an inner positive electrode terminal 5 and an inner negative electrode terminal 6, which are in contact with the front and rear terminals of the external battery housed in the housing. The front end surface of the housing is provided with an outer positive electrode terminal 3 connected to the inner positive electrode terminal, and the rear end surface of the housing is provided with an outer negative electrode terminal 4 connected to the inner negative electrode terminal. An output transistor 32 is disposed between the inner negative electrode terminal and the outer negative electrode terminal. A RFIC 35 generates, in accordance with a signal received via an antenna, a control signal for the output transistor. A current flowing in the output transistor is converted into a voltage by means of a detection resistor 31 that is provided in series to the outputtransistor. The voltage is detected by a current detection unit 33.
Description
technical field [0001] The present invention relates to a battery-type power supply unit having a wireless communication function. Background technique [0002] Patent Document 1 discloses a wireless reception drive device that can be mounted in a battery case of an external load device such as an electric toy. This wireless receiving drive device is configured as a so-called switching power supply, and changes the duty ratio of a drive signal of a transistor interposed between a stored battery and an external terminal in the wireless module according to a user instruction received through the wireless receiving unit, thereby By changing the driving voltage to drive the external load device, the action of the external load device such as electric toys can be controlled. Furthermore, it also includes the function of controlling the power supply of the wireless receiving part in linkage with the external switch of the external load device, so as to achieve the effect of delay...
