Abstract:
A circuit for a small electric appliance is disclosed. The circuit includes a battery (B); a control circuit (uC) for measuring the charging current of the battery (B); a DC-DC converter (DC/DC) which supplies the control circuit (uC) from the battery; and a current sensing resistor (R1), whose one end lies at a reference potential and whose other end is connected to the battery (B). The control circuit (uC) has a terminal which is at reference potential, and a measurement input which is related to the reference potential.
