New Products 8A100-1 and 8A100-2 Dual High-Current Photovoltaic Power Source
The 8A100-1 and 8A100-2 are dual high-current Photovoltaic Isolator (PVI) milli-watt power source.
These devices achieve the highest output current of any PVI on the market today
while providing a logic-level compatible output voltage.

** 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.

** SOIC MOS PRECISION ADJUSTABLE CAPACITOR ARRAY **

The C632 SOIC chip-capacitor array is available in a 8 lead SOIC,
enabling a multivalue MOS capacitor to be soldered directly to a pc board.

The C632 features easily selectable precise capacitor values from 1pF to 63pF.
These are adjustable in 1pF increments.

Samples of the C632 in SOIC packaging are available now.
Other multivalue arrays will soon be available.  Call or email for details.
