  • Patent number: 10763662
    Abstract: 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.

  • Patent number: 10763251
    Abstract: A semiconductor device has a protected line connected to a ground line by a triggered clamp. A variable shunt, which includes a depletion mode JFET, is connected between the protected line and the ground line, in parallel with the triggered clamp. The depletion mode JFET is formed in a substrate of the semiconductor device. The channel of the depletion mode JFET provides a resistive path for the variable shunt when the semiconductor device is unpowered, to dissipate charge from the powered line after an ESD event. When the semiconductor device is operated, that is, powered up, the gate of the depletion mode JFET may be biased to turn off the channel, and so reduce impairment of operation of the semiconductor device.
