Electronic device with short circuit protection element, fabrication method and design method
An electronic device includes: a control terminal, which extends on a first face of a substrate; a first conduction terminal, which extends in the substrate at the first face of the substrate; a first insulating layer interposed between the control terminal and the first conduction terminal; a conductive path, which can be biased at a biasing voltage; and a protection element, coupled to the control terminal and to the conductive path, which forms an electrical connection between the control terminal and the conductive path and is designed to melt, and thus interrupt electrical connection, in the presence of a leakage current higher than a critical threshold between the control terminal and the first conduction terminal through the first insulating layer.
Apparatus for Compensating for Resistance Tolerances of a Fuse for a Circuit and Line Driver for a Connection of a Communication Device
An apparatus for compensating for resistance tolerances of a fuse for a circuit, wherein the apparatus is particularly intended for use in a line driver for a communication device and includes a tolerance-affected fuse, a first resistor connected in series with the fuse, and a second resistor connected in parallel with the fuse and the first resistor, where the apparatus has, at a predefined ambient temperature, a resistance that corresponds to a desired total resistance, where the resistance of the second resistor is, depending on a power input into the apparatus in a fault state and/or depending on a predefined tolerance of the resistance of the apparatus, a multiple of that of the first resistor.

In example implementations, a printhead die is provided. The printhead die includes a substrate, a chamber layer formed on the substrate, a plurality of printing fluid ejection chambers coupled to opposite sides of the chamber layer and along a length of the chamber layer, and a top hat layer formed on the chamber layer and the plurality of printing fluid ejection chambers. The chamber layer includes a void to store printing fluid. The top hat layer includes an initial unsupported top hat layer portion over the void, wherein the initial unsupported top hat layer portion comprises a first end that is narrower than a second end.

A power control system for a battery system of a vehicle includes a first contactor, a second contactor, N fuses and N vehicle loads. An active sacrificial protection device includes a third contactor and a first fuse. The active sacrificial protection device is connected to a positive or negative terminal of the battery system. A current sensor is configured to sense a measured load current flowing through one of the first contactor and the second contactor. A battery management module is configured to selectively close the third contactor to reduce current flowing through one of the first contactor or the second contactor and selectively open the one of the first contactor or the second contactor after closing the third contactor.
Connector with integrated thermal cutoff device for battery pack
A temperature-sensitive battery connector is disclosed. The connector can include a connector body and at least one conductor mounted to the connector body and configured to convey a current signal used to measure voltage from a battery pack or battery cell to a battery management system (BMS). The connector can include a thermal switching device mounted to the connector body and thermally coupled to a terminal of a battery pack or a battery cell. The thermal switching device can be configured to provide an overtemperature signal to the BMS by changing or interrupting a current conducted by at least one conductor when a temperature of the battery pack or battery cell exceeds a threshold temperature.
CIRCUIT PROTECTION FOR HYBRID ANTENNA DISTRIBUTION UNITS
Some embodiments of the present disclosure are directed to a hybrid distribution unit that can distribute both power and data connections from a power and fiber cables (or from a hybrid cable containing both power and fiber) within a compact enclosure that helps reduce the overall footprint of the hybrid distribution unit mounted on a cellular tower. Some embodiments may also include circuit protection features, such as fuses or circuit breakers. Other embodiments may be described or claimed.
Electrochemical energy storage module and vehicle
An electrochemical energy storage module and a vehicle having an energy storage module of this type. At least one energy storage cell and at least one bridging device are electrically connected in parallel. The bridging device has a first current conductor having at least one bridging point, which has a bridging point cross-section, and a second current conductor, which is spaced apart from the first current conductor by a gap. The bridging device also has a bridging switch for establishing a first partial electrical connection between the first current conductor and the second current conductor and has a bridging material arranged in the region of the bridging point.
PRESSURE-COMPENSATED FUSE ASSEMBLY
A pressure-compensated fuse assembly may include a first chamber housing a first fluid and a plurality of solid particles. Additionally, the fuse assembly may include a second chamber housing a second fluid. Further, the fuse assembly may include a pressure compensator disposed between the first chamber and the second chamber. The pressure compensator may be configured to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber.
Fuse array for vehicle electrical system having multiple discrete circuits
A fuse array for use in a vehicle electrical system having more than one battery, such as in a start-stop vehicle that automatically shuts off an engine when the vehicle comes to a stop and automatically restarts the engine when a driver starts driving again. The fuse array includes first and second discrete circuits, where the discrete circuits include their own internal bus bars and are electrically isolated from one another, even though they are part of the same fuse array. This enables the fuse array to independently provide battery power to different downstream electrical components, such as a power distribution device and various high amperage components, while still utilizing a single compact assembly.
FUSE UNIT
A fuse unit includes: a fusible link which is connected to a battery terminal and of which a fuse is fused when overcurrent flows therein; and a holding mechanism including a base portion that is interposed between a post-standing surface and the battery terminal in a state in which the battery terminal is fastened to a battery post provided on the post-standing surface of a battery housing, and a holding portion that is connected to the base portion and holds the fusible link on the post-standing surface. Accordingly, a load acting on the battery post can be suppressed.
