    Abstract: A method and a circuit to achieve a low drop-out voltage regulator with a wide output load range has been achieved. A fast loop is introduced in the circuit. The circuit is internally compensated and uses a capacitor to ensure that the internal pole is more dominant than the output pole as in standard Miller compensation. The quiescent current is set being proportional to the output load current. No explicit low power drive stage is required. The whole output range is covered by one output drive stage. By that means the total consumption of quiescent or wasted current is reduced. An excellent PSRR is achieved due to load dependent bias current.

    Abstract: The invention refers to a charge/discharge protection circuit for a rechargeable battery, where the protection circuit is integrated on a single chip, including the fusible link, the load current switch and the short-circuit switch. This is achieved by dividing the functions of the fusible link, the load current switch, and the short-circuit switch into in parallel arranged T-sections, each of which is designed for only a fraction of the nominal load so that each of the easily integrated fuse segments carry only the respective fraction of the nominal current. It is important that the entire protection circuit or its control logic will not be destroyed before through an unduly high over-voltage, in which case the sequential melting of the fuse segments would no longer be guaranteed. This is handled by a semiconductor switch which short-circuits the over-voltage immediately.

    Abstract: The invention refers to a charge/discharge protection circuit for a rechargeable battery which is protected by a fusible link, where the rechargeable battery comprises a control logic which opens or closes a load switch depending on the magnitude of the battery voltage, the voltage on the charge/discharge terminals of the protection circuit and the charge/discharge current. The protection circuit is designed so that the electric strength needs to match only the actual maximum battery voltage, thus requiring little real estate on an IC chip and also allowing most components to be integrated.
