摘要： Two-wire, electronic switch which performs sensing functions, measurement functions, and output-control functions for an electrical load without receiving power from a power source, external or internal, other than the power source for the electrical load that is controlled by the switch. Electronic components of a two-wire, electronic switch which is fabricated in accordance with the present invention obtain power: (a) when the switch is off, from a power source which drives a load which is controlled by the switch and (b) when the switch is on, from an output of devices which convert current to voltage and which receive at least a portion of a current through the load as input.

摘要： A solid-state, four terminal optical relay has a current regulator with two input pins, and an output switch with two output pins. The relay includes an optical isolator assembly so that the current which causes switching of the relay is optically, rather than electrically, transmitted to an output switch driver. The relay includes an internal current overload detect and latch circuit which operates if the relay is switched on into a shorted load, or if a short is switched in across the load while the relay is on. The current overload detect and latch circuit is sufficiently fast to permit the relay to be continuously pulsed into a shorted load without damage to the relay.

摘要： A power FET is driven by a photodiode chain across a switch, which has two FETs (5, 6) arranged in series. Upon illumination the first FET (5) is driven to be conducting, which permits current to flow from a capacitor (C) connected to a fixed voltage into the gate-source capacitor (C.sub.GS) of the power FET (1) and to switch it on rapidly. Upon cessation of the illumination, the first FET (5) is blocked while the second FET (6) is driven to be conducting. Hence, the C.sub.GS of the power FET is discharged and the power FET is blocked.

摘要： A semiconductor switching circuit comprises an output FET receiving a photovoltaic output generated by a diode array responsive to a light signal from a light emitting element, a depression mode driving FET connected at the drain and source to the gate and source of the output FET, and a constant voltage conduction element connected in parallel with a resistor connected across the gate and source of the driving FET. The sensitivity of the circuit is elevated by setting the value of this resistor relatively high, whereas high speed operation can be assured by having discharge current of an accumulated charge across the drain and gate of the output FET bypassed through the resistor.

摘要： A photovoltaic relay which includes a unique pull down circuit for rapidly turning off the relays field effect transistor(s). The pull down circuit discharges the gate-to-source capacitance of the relay's field effect transistors by turning on a thyristor by turning off a light-activated switch connected between the gate and the cathode terminals of the thyristor. In one integrated circuit embodiment, the light-activated switch is energized by the same light source which activates the photodiode stack which drives the relay. The presence of the pull down circuit does not effect the turn on time of the relay.
