Fuzzy-logic, noise-free, f-SPDT Solid-State Drivers
A unique feature of an f-SPDT driver is a fuzzy- logic control and power source for the
internal logic and drivers. The control input designed for the maximum application flexibility and
simplicity in interfacing. It is a high impedance input and any 5V CMOS logic can be used to control
it. The best result can be obtained with tri-state output logic, like bus-driver IC chips or CPUs. The
control input has three defined levels, as that can be seen on the figure, below: 0-1.7V, 1.9-3.2V, and
3.4-5V. That voltage variation allows targeting control any one of terminals or turn “OFF” the driver

Full-Bridge Drivers (H-Switch) for DC Motors
EDR’s H-driver family of drivers provides significant competitive advantage in the power
driver market. An internal precision timer controls a “dead” time between the CW and CCW and
provides true break-before-make commutation that allows driver a high-speed solenoid and not
to worry about a shoot-through current. The enable input is a dual function control. It disables
both outputs (terminals) and cuts external power consumption to the minimum (stand-by)...
