Power IC Relay

Single-Pole, 500mA, 0-100V DC

General Description

The Photovoltaic DC Relay (PVD) is a single-pole, nor-

mally open solid state replacement for electro-me-

chanical relays used for general purpose switching of

analog signals. It utilizes as an output switch a unique

bidirectional (AC or DC) MOSFET power IC termed a

BOSFET. The BOSFET is controlled by a photovoltaic

generator of novel construction, which is energized by

radiation from a dielectrically isolated light emitting di-

ode (LED).

The PVD overcomes the limitations of both conven-

tional and reed electromechanical relays by offering

the solid state advantages of long life, high operating

speed, low pick-up power, bounce-free operation, low

thermal voltages and miniaturization. These advan-

tages allow product improvement and design innova-

tions in many applications such as process control,

multiplexing, telecommunications, automatic test

equipment and data acquisition.

The PVD can switch analog signals from thermocouple

level to 100 volts peak DC. Signal frequencies into the

RF range are easily controlled and switching rates up

to 2kHz are achievable. The extremely small thermally

generated offset voltages allow increased measure-

ment accuracies.

Unique silicon technology developed by International

Rectifier forms the heart of the PVD. The monolithic

BOSFET contains a bidirectional N-channel power

MOSFET output structure. In addition, this power IC

chip has input circuitry for fast turn-off and gate protec-

tion functions. This section of the BOSFET chip utilizes

both bipolar and MOS technology to form NPN transis-

tors, P-channel MOSFETs, resistors, diodes and ca-

pacitors.

The photovoltaic generator similarly utilizes a unique

International Rectifier alloyed multijunction structure.

The excellent current conversion efficiency of this tech-

nique results in the very fast response of the PVD mi-

croelectronic power IC relay.

This advanced semiconductor technology has created

a radically new control device. Designers can now de-

velop switching systems to new standards of electrical

performance and mechanical compactness.
