Abstract: A communication device for connection with a power source and a host device is provided. The communication device comprises a device controller and a converter circuit. The device controller is adapted for data communication with the host device and the converter circuit is configured to provide a virtual device ground at least to the device controller, so as to compensate a ground potential difference between the host device and the communication device.

Abstract: A power converter includes an inductor, boost and buck circuits, and a controller circuit. The controller circuit is configured to determine a current through the inductor, generate a buck reference for comparison with the current to control operation of the buck circuit, calculate a variable offset based upon input and output potentials of the power converter and apply the variable offset to the buck reference to generate a boost reference, compare the boost reference with the current to control operation of the boost circuit, and, based upon comparisons of the current with the buck reference and the boost reference, respectively, operate the boost circuit and the buck circuit.

Abstract: A system for transmitting power and data through a two pin connection interface may have a first device having a power source, a first microcontroller with a first communication peripheral coupled with a first pin and a first control port coupled with a gate of a first MOSFET whose switch path couples the power source with the first pin; and a second device having a battery, a second microcontroller with a second communication peripheral coupled with a first pin and a second control port coupled with a gate of a second MOSFET whose switch path couples the battery with the first pin of the second device. When the devices are coupled, the MOSFETs are synchronously turned on and off, wherein during an off-cycle a data transfer between the first and second device takes place through the first and second communication peripherals of the first and second device, respectively.
