Abstract: Control device for controlling a switch in a charging line disposed between a first power line and a second power line in a power distribution architecture. The control device includes a current level input for receiving a current measurement of the current conducted through the charging line, a voltage level input for receiving a voltage measurement of the voltage applied on the charging line. A monitor monitors the relationship between the current and voltage measurements and generates a control signal for controlling the switch in response to a coherent change in the current and voltage measurements exceeding a threshold. A control signal is not generated when a change in one of the current and voltage measurements exceeding a threshold is not associated with a coherent change in the other of the current and voltage measurements.

Abstract: A microcontroller is provided with a plurality of slave drive units for driving peripheral devices. Individual speed units are provided that have serial shift registers, multiplexors, and duplex data communication connections with individual serial registers of respective slave drive units of a series chain. In a first cycle or mode, a serial data connection between the serial shift registers of the speed units causes data to be serially communicated, at a first relatively faster pulse rate, from the microcontroller into the data input of the series chain and to the microcontroller from the data output of the series chain. In a second cycle or mode, for each pair of single speed unit and slave drive unit, the duplex data communication between the serial shift registers of the pair causes, at a second relatively slower pulse rate, data to be serially communicated in parallel therebetween.

Abstract: An electrical safety system comprises a main safety device including a N-type transistor and an auxiliary safety device including a P-type transistor, alternately activated under command of a controller. The N-type transistor and the P-type transistor have the function of overcurrent protection, respectively in a first operating mode and in a second operating mode. The auxiliary safety device includes a passive component, connected in series with the P-type transistor, for providing a voltage drop when a current passes through the passive component, and a driving circuit for turning off the P-type transistor under control of the voltage drop exceeding a first threshold, in the second operating mode.

Abstract: This publication describes apparatuses and methods for driving a switching device and providing for the fast start-up of the switching device. In an aspect, the apparatus includes a driver circuit and a starter circuit. The driver circuit for applying control signals to a control terminal of the switching device when activated. The switching device is activatable to drive a load in an operating mode when a control signal above a threshold voltage is applied to the control terminal. The starter circuit is coupled to the control terminal and includes an energy store and a switch operable to discharge the energy store to deliver a start-up voltage above the threshold to the control terminal. As such, the switching device can be activated during a delay period before the driver circuit can generate a control signal above the threshold voltage after being activated.
