- two primary lithium type batteries are used, which generate a potential of 3V volts each. These two batteries are connected in series internally in the equipment box to generate a voltage of 6 volts with which the LDO voltage regulator described above is also fed.
- the positive 5-volt power supply is designed with a DC / DC type integrated circuit model TPS 61220 whose schematic is presented in the previous table.
- the 5 volt negative source included in the printed circuit of the stimulator is designed with an inverter type TPS63700 integrated circuit whose schematic is presented in the previous table.
- Both sources of power of 5 volts are controlled by means of the micro controller (7) who through the pin 41 of the same can turn off and ignite the operation of the same.
- the electronic circuit responsible for recharging the internal batteries is designed to intelligently charge both lithium-ion batteries and lithium-ion polymer type batteries. In the case of this equipment you can use any of these batteries whose physical dimensions allow their installation inside the plastic box. In the case of this equipment, batteries with a physical dimension of 40x60x6mm and a load capacity of more than 850 milliamperes have been used, thus allowing an autonomy of operation of the equipment exceeding 30 hours.
- the other type of rechargeable battery that can be used in this equipment is a pyramidal type Lithium Ion usually used in cellular mobile telephony whose charging characteristics are similar to the aforementioned Lithium Ion Polymer.
- the equipment can be powered with primary Lithium AA batteries.
- the equipment can be used by means of two lithium-type primary batteries which have an energy storage of approximately 1.20 amps and a working voltage of 3 volts. If this type of power is used, two batteries connected internally in series are required, which allows the equipment to operate for 50 hours.
