Photovoltaic Isolator 5-10 Volt Output
General Description Features
The PVI Photovoltaic Isolator generates an electri- Isolated Voltage Source ■ cally isolated DC voltage upon receipt of a DC input signal. The input of the PVI is a light-emitting diode MOSFET Driver ■ (LED) which is optically coupled to, but electrically Up to 10µA Output ■ isolated from, the output. A GaAIAs LED is used for Fast Response ■ high output and maximum stability. The infrared emission from the LED energizes, by photovoltaic GaAIAs LED ■ action, a series connection of silicon PN junctions. A 2500V (RMS) Isolation ■ unique alloyed junction stack which is edge-illumi- 8-pin DIP Package ■ nated is used to form the output photovoltaic genera- tors. This novel structure produces extremely high Single or Dual Output ■ operating efficiency. Units are available with a single 5-volt output or dual 5-volt outputs which can be series connected to produce 10 volts. A PVI can serve as an isolator, a coupler and as an isolated voltage source. As an isolator, the PVI can serve as the key component in a solid state relay cir- cuits. The PVI is ideally suited for driving power MOS- FETs and IGBTs or sensitive gate SCRs to form solid state relays. As a coupler, the PVI can sense a low-level DC sig- nal and transmit a voltage signal to an electrically remote circuit. As a voltage source, the PVI can function as a ‘DC transformer’ by providing an isolated, low-current DC source for biasing or supplying power to low quiescent current electronic devices. Conventional optocouplers merely modulate the resistance of an output device such as a transistor, diode or resistor. Such optocouplers require a sepa- rate voltage source to detect the presence of an
