DIONICS, Inc., the inventor of the
Photovoltaic (PV) optically-isolated MOSFET driver, is a
major contributor to the advancement of the state-of-the-art
in PV optically-isolated Solid State Relays. In addition to
expertise in micro-Photovoltaics (µPV), we pioneered the
use of Dielectric Isolation processing for monolithic high-voltage
IC's used in gas-discharge digital displays.
We supply designers and manufacturers with the highest quality:

About our patented active
dynamic discharge circuitry
..
Our
ISO-gate microcircuits designated DIG-11-8-30-DD,
DIG-12-8-30-DD, DIG-22-8-30-DD and DIG-11-15-30-DD are
optically coupled floating power sources used primarily to
control power MOSFETS when electrical isolation between input
and output is required. The dynamic discharge circuitry
additionally causes rapid, active turn-off of the MOSFET when
power to the input LED is interrupted.
The
patented dynamic discharge feature (US Patent 4,931,656)
guarantees break before make in most solid state relay
switching applications. And, since the turn-off is active,
the DD series is particularly effective for application in
noisy environments such as motor controllers.
Prior to
the development of the DD series, photovoltaic MOSFET drivers
(ISO-GATES) consisted simply of an LED light source optically
coupled to a photovoltaic diode array. Circuitry to discharge
the MOSFET gate capacitance was either a resistor sized to
compromise the turn-on/turn-off time or some elaborate
multi-component turn-off scheme.
All of the above devices are available in a
variety of packages including gull-wing or straight leg
plastic DIPs and ceramic military packaging.
