  • Selectable current limiter circuit
    Patent number: 9948242
    Abstract: A selectable current limiter circuit to limit the current an amplifier with a load. The limiter circuit limits the current of an amplifier by comparing a voltage reference that follows the output swing of the amplifier to voltage drop across a current limiting resistor coupled to the output of the amplifier. The limiter circuits are operatively coupled to buffer and switch circuits that delay the current limiting until the limiter circuits are activated.
