Abstract: Vehicle power distribution circuit for connecting between a battery and a power line connected to a generator or DC/DC-Converter. The circuit has a charging line connecting the battery to the power line for charging the battery when a forward voltage is applied by the generator or DC/DC-Converter. An ideal diode arrangement is provided in the charging line for conducting a forward current from the generator or DC/DC-Converter to the battery when the forward voltage is applied. The ideal diode arrangement prevents conduction of a reverse current from the battery to the power line when a reverse voltage is applied.

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: A switching circuit has a primary MOSFET switch connected between first and second terminals that are connected to a power line and a load represented as a resistance and inductance. The primary switch is operable by primary control commands to assume a conductive or non-conductive state. Four protection branches are connected in parallel with the primary switch, each having a series connected resistive element and a secondary MOSFET switch operable by branch control commands received at branch command terminals to assume a conductive or non-conductive state. A timing circuit applies branch turn off control commands in sequence to the branch command terminals, each delayed by a different predetermined time interval relative to when a primary turn off control command is applied to the primary switch.

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 vehicle power distribution circuit for connecting between an energy store and a power line connected to a generator or DC/DC-Converter. The circuit has a charging line connecting between the energy store and the power line for charging the energy store when a forward voltage is applied by the generator or DC/DC-Converter. A protection switch is provided in the charging line and is openable for preventing conduction of current through the protection switch in response to a drop in voltage on the power line. An ideal diode arrangement is provided in parallel to the protection switch in the charging line for conducting the forward current from the generator or DC/DC-Converter to the energy store. The ideal diode arrangement prevents the conducting of a reverse current when a reverse voltage is applied.

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.

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.
