  • Patent number: 8213147
    Abstract: An over-current protection circuit is disclosed that provides a current limit threshold using resistors in the path of a scaled mirror current of a load current. The protective circuit has a first state that passes a supply source to a device, but when the threshold is reached the circuit becomes a feedback circuit that allows only a set final current to be passed to the device. When the load current reaches the threshold, the mirror current reaches a corresponding threshold that triggers a comparator and circuitry that then limits and fold backs the load current.

  • Patent number: 8179151
    Abstract: The present invention employs identically sized mirror transistors arrange in groups that may be preferentially addressed and activated to determine the value of a resistor. Known current are directed through the resistor, and the voltage developed is measured by comparing against a reference voltage. The current is increased or decreased by the least significant value until the voltage across the resistor matches the reference voltage. A successive approximation or other known technique may be used instead. A reference current is developed that temperature stable and that is trimmed when manufactured to reduce process effects. The reference voltage may be constructed to be independent form a local power source so that the system is relatively independent of process, voltage and temperature, PVT.
