Abstract: In described examples of a circuit that operates as a low-power ideal diode, and an IC chip that contains the ideal diode circuit, the circuit includes: a first P-channel transistor connected to receive an input voltage on a first terminal and to provide an output voltage on a second terminal; a first amplifier connected to receive the input voltage and the output voltage and to provide a first signal that dynamically biases a gate of the first P-channel transistor as a function of the voltage across the first P-channel transistor; and a second amplifier connected to receive the input voltage and the output voltage and to provide a second signal that acts to turn off the gate of the first P-channel transistor responsive to the input voltage being less than the output voltage.

Abstract: USB controllers, systems and methods are presented to conserve power in a USB controller, in which a transmitter transmits data to a line of a connected USB cable according to a transmit data signal, and a pull down circuit selectively sinks current from a supply node of the transmitter when the transmit data signal is in a first state, refrains from sinking the first current from the supply node when the transmit data signal is in a different second state.

Abstract: A current mirror includes a first pair of transistors, wherein gates of the first pair of transistors are connected together, and a second pair of transistors coupled to the first pair of transistors. Gates of the second pair of transistors are connected together. A first resistive device is coupled across a drain and a source of one of the transistors of the second pair of transistors. A second resistive device is coupled across a drain and a source of the other transistor of the second pair of transistors. The first pair of transistors are configured to operate in weak inversion at an input current to the current mirror within a first current range and the second pair of transistors are configured to operate in strong inversion at an input current within a second current range.

Abstract: Protection circuits, USB interface integrated circuits, and methods for protecting host circuitry from USB port pin overvoltages, in which a switch is connected between a USB port pin and a middle node, and a detection circuit compares the middle node voltage with a reference voltage. A control circuit turns off the switch and turns on a clamp circuit to conduct pull down current from the middle node in response to the middle node voltage exceeding the reference voltage to mitigate overvoltage conditions on a host pin coupled to the middle node. When the middle node voltage falls below the reference voltage, the control circuit delays for a predetermined time and then turns off the clamp circuit and turns on the switch.

Abstract: A circuit and method for providing a current limiting feature in a low dropout (“LDO”) linear voltage regulator. A pass element generates an output voltage that is less than the input voltage. The pass element is normally enabled by an error amplifier that compares a feedback signal from the output of the pass element with a reference signal. However, the pass element may be enabled by a current limiting circuit that bypasses the error amplifier to limit the current generated at the output of the pass element.
