Techniques for charging an electronic device using a Universal Serial Bus (USB) cable and connector are provided. In an example, an apparatus can include a charger, a USB cable coupled to the charger at a first end of the cable, a paddle card for a USB connector coupled to the cable at a second end of the cable, the paddle card including differential data contacts, and wherein the differential data contacts of the paddle card are shorted together at the paddle card.

USB Type-C connector with shorted differential data contacts

A paddle board includes an electronic marker circuit configured to indicate at least one capability of a cable assembly to a device coupled to the cable assembly and to select the device as one of a source or a sink, the paddle board being powered by the device, a register configured to store at least one variable value associated with at least one of the cable assembly and the paddle board, and a temperature sensor configured to sense a temperature of the paddle board and configured to store a value indicating the sensed temperature in the register.

Self identification and pollution detection in USB Type-C

This document discusses, among other things, apparatus, systems, and methods to prevent a voltage of a charging battery from exceeding a voltage threshold, including receiving charging information from a battery and controlling an output current of a travel adapter, including adjusting the received battery current information using a load current to prevent the voltage of the battery from exceeding a voltage threshold, and providing output current limit information to the travel adapter using the adjusted battery current information.

Battery charge termination voltage reduction

A device includes an interface configured to couple a power source to the device. The interface includes a plurality of contacts including at least one first contact configured to couple a voltage bus of the power source to a voltage bus of the device, and at least one second contact configured to couple the voltage bus of the power source to a secondary bus of the device. The device further includes a detector configured to determine a contact resistance of the at least one first contact based on a first current associated with the voltage bus and a second current associated with the secondary bus.

High contact resistance detection

This document discusses, among other things, apparatus and methods to optimize charging of a battery, including providing a first charge profile configured to provide charge current pulses to a battery in a plurality of steps. In the first charge profile, the charge current pulses can be stepped down in the plurality of steps using a comparison of a terminal voltage of the battery to a clamp voltage. When the terminal voltage meets or exceeds the clamp voltage, a high time current of the charge current pulse can be decreased and the clamp voltage can be increased before providing a subsequent charge current pulse.

This document discusses among other things, methods and apparatus to conserve energy when providing proximity information. An example apparatus can include an energy emitter configured to emit a first pulse of energy, an energy sensor configured to receive reflected energy from the first pulse of energy, a control circuit including a processor, the processor configured to provide first proximity information of the apparatus with respect to an object using the reflected energy. The control circuit can be configured to control the energy emitter, to compare the first proximity information with second proximity information, and to modulate a delay between the first pulse of energy and a subsequent pulse of energy using the comparison.

Adaptive response time acceleration

This document discusses, among other things, systems and methods to communicate data over a data bus during a first period of a clock signal with a uniform power distribution, including providing a complimentary bit state of the data during a first portion of the first period of the clock signal and providing an actual bit state of the data during a second portion of the first period of the clock signal. In an example, the first period can include first, second, third, and fourth portions, and the systems and methods can include providing a complimentary bit state of the data during first and fourth portions of the first period of the clock signal and an actual bit state of the data during a second portion of the first period of the clock signal.

Complimentary bit slicing side channel attack defense

Apparatus and methods are provided for defending an electronic circuit secret algorithm and secret parameter values against a side-attack. In an example, a method can include receiving first one or more parameters for altering a clock signal of the electronic device at a non-volatile memory register, and altering a frequency of the clock signal of the electronic device during execution of an authentication routine according to the first one or more parameters.

In one general aspect, a repeater can include an input terminal configured to be coupled to a first portion of a MIPI signal path. The MIPI signal path being a unidirectional path between a receiver and a transmitter, the input terminal configured to receive a set of signals from the receiver via the MIPI signal path. The repeater can include an output terminal configured to be coupled to a second portion of the MIPI signal path, the first portion of the MIPI signal path and the second portion of the MIPI signal path having a combined distance greater than 30 centimeters.

Methods and apparatus related to a repeater

This document provides apparatus and methods for providing low latency response from a processor to the interrupts collected from peripheral devices. In an example, an apparatus can collect interrupt requests from a plurality of peripheral devices, and can communicate interrupt information to a processor. Certain examples can reduce the quantity of processor general purpose inputs and outputs configured to receive the peripheral device interrupts in comparison to systems where the peripheral device interrupts are directly coupled to the processor.
