Abstract: The present disclosure generally relates to biasing an isolation region in a semiconductor substrate. In an example, an integrated circuit includes a semiconductor substrate, a first rectifying device, and a second rectifying device. The semiconductor substrate has a first region, a second region, and a third region each being an opposite conductivity type from the semiconductor substrate. The first region and the second region are respective current terminals of a transistor. The first rectifying device has a first positive terminal and a first negative terminal. The first positive terminal is coupled to the first region, and the first negative terminal is coupled to the third region. The second rectifying device has a second positive terminal and a second negative terminal. The second positive terminal is coupled to a ground terminal, and the second negative terminal is coupled to the third region.

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: Disclosed examples include ICs and general-purpose I/O circuitry to facilitate interfacing of the IC with a variety of external circuits operating at different supply voltages, in which an integer number N supply drive circuits are individually coupled with a corresponding supply voltage node and selectively connect the corresponding supply voltage node to a general-purpose output node based on a supply drive control signal to allow programmable interfacing of individual general-purpose output pads or pins of the IC with an external circuit at the appropriate signal level.
