Abstract: A bus microcontroller includes a processor circuit having at least one unit designed for performing one or more functions due to a bus command via a communication bus, a power control circuit adapted to be coupled to a transmitter-receiver circuit for receiving bus messages via the communication bus, and a means for placing at least part of the processor circuit into a reduced-power operating mode without placing the entire processor circuit into the reduced-power operating mode. The power control circuit is designed to evaluate incoming bus messages with respect to an activation bus message containing information on activating at least part of the processor circuit, and to output a corresponding activation control signal. The bus microcontroller also includes means for activating at least a part of the processor circuit that is placed in a reduced-power operating mode, in response to output of an activation control signal of the power control circuit.

Abstract: A bandgap reference voltage generator includes a bipolar assembly having a first resistor, a first branch and a second branch that is in parallel with the first branch. The first branch includes a first bipolar transistor with a base coupled to a fixed voltage. The second branch includes a second bipolar transistor with a base coupled to the fixed voltage and a second resistor coupled in series with the second bipolar transistor. A differential module is coupled to the first and second bipolar transistors and configured to balance the currents in the first and the second branches. The bandgap reference voltage is output at a node to which the first resistor is connected.

Abstract: A method and an active battery balancing circuit for balancing an electric charge in a plurality of cells of a battery that are electrically connected in series is disclosed. A first subset of the cells of the battery is electrically connected to an inductance for providing a current flow from the first subset through the inductance. The first subset of the cells is disconnected from the inductance, and a current is allowed to flow from the inductance into a second subset of the cells of the battery. At least one of the first and the second subset of the cells of the battery comprises two or more cells.

Abstract: An NFC controller analyzes incoming commands, by name, and decides, according a predefined name table, to which secure element the actual command and following commands are sent for processing.

Abstract: A battery includes a battery module that includes a plurality of submodules electrically connected in series. Each submodule comprises first and second submodule terminals and a cell. At least one submodule in each battery module is a switchable submodule comprising a submodule switching circuit. The submodule switching circuit is switchable between a first state and a second state. The submodule switching circuit electrically connects the cell of the switchable submodule between the first and second submodule terminals when the submodule switching circuit is in the first state. The submodule switching circuit provides an electrical bypass connection between the first and second submodule terminals and the cell of the switchable submodule is electrically disconnected from at least one of the first and second submodule terminals when the switching circuit is in the second state. The battery further comprises a control unit for operating the switching circuit of each module.
