Embodiment 1
[0023] figure 1 It is a block diagram showing the configuration of the battery pack and the portable electronic device according to the first embodiment of the present invention. in figure 1 Among them, a portable electronic device (main body side) has a CPU 10, a main authentication circuit 11, and a resistor R1. On the other hand, on the battery pack side, a sub-certification circuit 21, thermistor TH, and battery BAT are provided. In addition, portable electronic devices are devices such as mobile phones, portable information terminals (including composite information terminals such as digital still cameras and digital video camera functions), and various circuits that enable the portable electronic devices to function are mounted on the body side of the device. , But it has nothing to do with the present invention, so its description is omitted. Also, on the battery pack side, in addition to the above-mentioned subordinate authentication circuit 21, thermistor TH, and batte...
Embodiment 2
[0050] Figure 6 It is a block diagram showing the structure of a battery pack and a portable electronic device according to the second embodiment of the present invention. in Figure 6 Among them, the portable electronic device (main body side) has a CPU 10a, a main authentication circuit 11a, a resistor R1, switches S1, and S2. On the other hand, the battery pack side has an authentication circuit 22a, a thermistor TH, a voltage adjustment circuit 25, a comparator 26, an inverter circuit INV, and switches S3 and S4. Here, the voltage adjustment circuit 25 and the comparator 26 constitute a potential correction circuit 23a. In addition, as the components constituting the subordinate authentication circuit on the battery side, the authentication circuit 22a, the voltage adjustment circuit 25, the comparator 26, the inverter circuit INV, and the switches S3 and S4 are included. In addition, on the main body side, as in the first embodiment, various circuits and the like for enabli...
