Abstract: Disclosed is a system for aiding in determining when a power-providing outlet is ending its usable service life and is due for service or replacement. A connection detection unit and counting unit respectively monitor connection of a device to a port and maintain a connection count of connection events. For USB type C connections a cable or device resistance detection circuit can be used to determine if a USB type C device or cable has been connected. USB Type A and AC connections can be detected by mechanical or electrical mechanisms. When a connection has been detected a counter can be incremented or decremented to record a connection. A limit value can be set and compared to the connection count and a sensory or electronic indication can be made when the limit value is exceeded.

Abstract: A system to regulate the temperature of a Source Port that includes a Port Controller having a first source power capabilities list stored thereon in a non-transitory digital media, the source capabilities list identifying a plurality of first power delivery capabilities that, based on their power requirements, may be negotiated by the Port Controller, a temperature sensor that measures a temperature of the power system and communicates that measured temperature to a comparator. The comparator compares the measured temperature to predefined limit temperatures and when the measured temperature crosses a predefined limit temperature threshold, the first source capabilities list being replaced with a second source capabilities list identifying a plurality of second power capabilities that, based on their power requirements, may be connected to the Source Port.

Abstract: Control circuitry handles inrush current, and may provide under voltage and/or over voltage monitoring and handling, as well as remote enable handling. The circuitry may advantageously employ a sense capacitor in parallel with an input capacitor (e.g., bulk input filter capacitor), and a current mirror to produce a signal proportional to input current. A clamp circuit may control a series pass device to regulate current in response to the proportional signal, or to interrupt current flow in response to an under voltage or over voltage condition or receipt of a signal indicative of a disable state. An enable signal may be summed into a comparator that handles under voltage condition determination.

Abstract: A power converter provides current limit/current share functionality, allowing use in a point-of-load architecture and/or in parallel with one or more other power converters. An inner current control loop may sense output current over only a portion of a duty cycle, for example at a low side active switch. The resulting signal is compensated, and may be level shifted, for example via a resistor divider network, and supplied to a current control amplifier. An outer voltage control loop may sense output voltage, and provide a voltage error signal from a voltage error amplifier to the resistor divider network. Power converters are operable as masters or slaves, and include sense input and trim input terminals.

Abstract: An auxiliary power supply or bias voltage supply employs a step up switch mode DC/DC power converter topology to supply regulated bias supply voltages, from very low input voltages (e.g., less than 2V). The supply will synchronize to dynamic loads making it particularly useful in circuits with periodic high peak current power demands, for example, gate drive circuits employed in regulated switched mode power converters. When unladed, the supply will efficiently adjust its cycle period to the minimum required to maintain the desired boosted output voltage. Additional transformer windings or a charge pump may be used to generate additional vias voltage sources.
