摘要: A two-terminal electronic fuse device involves two switches, four diodes, switch control circuitry, and a storage capacitor, connected in a particular topology. When AC current flows through the fuse, a charging current charges the storage capacitor. Energy stored in the storage capacitor is then used to power the switch control circuitry. If the voltage on the storage capacitor drops, then the switches are opened briefly and at the correct time. Opening the switches allows the charging current to flow. By opening the switches and charging the storage capacitor only at times of low current flow through the fuse, the disturbance of load current flowing through the fuse is minimized. If an overload current condition is detected, then the fuse has tripped and first and second switches are opened. If the capacitor does not need charging and there is no overload condition, then the switches remain closed.

摘要: Embodiments include techniques for automatically restarting a voltage foldback circuit, the techniques include operating a circuit, and detecting a condition of the circuit. The techniques also include performing a foldback operation based at least in part on the condition of the circuit, subsequently detecting the condition of the circuit. The techniques include initiating a timer of the circuit based at least in part on the subsequent detection of the circuit, and returning the circuit to normal operation based on the timer.

摘要: A solid state power controller, SSPC, having an input to receive supply current and an output for providing output current to a load in response to connection to the power supply, the solid state power controller further comprising at least one solid state switch and a controller to limit the power dissipated in the solid state power switch based on a measured voltage across the solid state switch and a predetermined power dissipation threshold for the SSPC to adjust the output current or voltage control signal of the solid state switch such that the actual power dissipation of the SSPC does not exceed the threshold.

摘要: The invention provides an alarm processing circuit including: a plurality of abnormality detection circuits (9-0 to 9-n) which detect different abnormalities and output alarm signals respectively; signal conversion circuits (13-1 to 13-n) which convert the alarm signals outputted from the plurality of abnormality detection circuits into time signals with unique time widths corresponding to kinds of the abnormalities respectively; and a determination circuit (21) which determines the kinds of the abnormalities respectively based on the time widths of the time signals outputted from the signal conversion circuits. Thus, it is possible to simplify the configuration and reduce the cost.

摘要: In a power supply control apparatus (11), a control circuit (23) adjusts a resistance between a drain and a source of a semiconductor transistor (20) by adjusting the voltage at a gate of the semiconductor transistor (20). After the control circuit (23) has lowered the resistance between the drain and the source, a control portion (56) determines whether or not the voltage at the source detected by a voltage detecting portion (21) is larger than or equal to a standard voltage. If it is determined by the control portion (56) that the voltage at the source is larger than or equal to the standard voltage, the control circuit (23) again lowers the resistance between the drain and the source. If it is determined by the control portion (56) that the voltage at the source is smaller than the standard voltage, the control circuit (23) adjusts the resistance between the drain and the source to a resistance at the time when determination was performed or larger.
