General Description

Features

The PVI Photovoltaic Isolator generates an electri-

cally isolated DC voltage upon receipt of a DC input

signal. The input of the PVI is a light-emitting diode

(LED) which is optically coupled to, but electrically

isolated from, the output. A GaAIAs LED is used for

high output and maximum stability. The infrared

emission from the LED energizes, by photovoltaic

action, a series connection of silicon PN junctions. A

unique alloyed junction stack which is edge-illumi-

nated is used to form the output photovoltaic genera-

tors. This novel structure produces extremely high

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

input signal. In contrast, a PVI actually transmits (and

transforms) energy across the isolation barrier and

directly generates an output voltage. This DC volt-

age, available at a 2500VAC isolation level, gives cir-

cuit designers a new and uniquely useful electronic

component.

Application Note:

The outputs of the PVI1050 (pins 5-6 and 7-8) may be placed in series connection to produce a 10-volt output

with a 5µA minimum short circuit current. Alternatively, the two ouptut of the PVI1050 may be connected in paral-

lel to produce a 5.0-volt ouput with a 10µA minimum short circuit current.

The two outputs of the PVI1050 may be applied separately with a maximum 1200VDC between the outputs.

Input-to-output isolation to either output is 2500V (RMS).
