Charge/Discharge Protection Circuit

A charge/discharge protection circuit with n parallel load current switches and a control logic for the latter, which in an over-voltage event disconnects the battery from the charge/discharge terminals through sequentially controlled melting of integrated fusible links, where the control logic in an over-voltage event, simultaneously closes all load current switches, then following sequentially opens a first number of the load current switches, and at the same time closes the switch segments of a short-circuit switch array associated with the respective load current switch, so that the associated fusible links melt sequentially. After the opening of this first number of load current switches the latter closes again and at the same time the remaining number of still closed load current switches opens, as well as continues to sequentially close the remaining switch segments.
