Optoisolators - Transistor, Photovoltaic Output

The HCPL-570K#2000 is an optoisolator designed to separate a control-signal electrical circuit from a field-side electrical circuit. The device can be used in a wide range of applications, including motor speed control, temperature control, and digital-to-analog conversion. In general, optoisolators provide isolation between input and output circuits, often accomplished by using an isolation barrier such as an insulator.

Working Principle

The HCPL-570K#2000 utilizes a phototransistor output (PTR) working on the photovoltaic principle. A light-emitting diode (LED) is used to convert electrical energy into optical energy, which is then detected by a phototransistor in order to drive the output. The electrical energy is converted into optical energy as the LED emits photons when an electrical current is passed through it. The photons are then detected by the phototransistor, which works on the principle that the phototransistor absorbs photons and responds by changing its conductance according to the amount of photons absorbed. The phototransistor then acts as a kind of electrometer and sends out its signal via a transistor switch.
