| description | A charging current control circuit for a medical instrument belongs to the field of medical instruments and is characterized in that a pin of a charging chip is connected with a plurality of divider resistors through an analog switch, the resistors are connected to ports of the analog switch, switches of the ports of the analog switch are connected with a main control chip, and the analog switch controls opening and closing of channels through an io port of the main control chip. The common end of each analog switch is connected with the ISET pin of the charging chip, the analog switches are connected with the control port of the main control chip at the same time, the charging current is controlled according to the actual situation by externally configuring the controllable resistor and adjusting the charging current, and it is avoided that the service life of a battery is shortened due to damage to the battery caused by repeated charging of equipment; and meanwhile, the situation that the current part of th |
