Description
The FOD3181 is a 0.5A Output Current, High Speed
MOSFET Gate Drive Optocoupler. It consists of a
gallium aluminum arsenide (AlGaAs) light emitting diode
optically coupled to a CMOS integrated circuit with a
power stage. The power stage consists of a PMOS pull-
up and a NMOS pull-down power transistor. It is ideally
suited for high frequency driving of MOSFETs used in
Plasma Display Panels (PDPs), motor control invertor
applications, and high performance DC/DC converters.
The device is packaged in an 8-pin dual in-line housing
compatible with 260°C reflow processes for lead free
solder compliance.

IOH and IOL Test Conditions
This device is tested and specified when driving a complex
reactive load. The load consists of a capacitor in the series with
a current limiting resistor. The capacitor represents the gate to
source capacitance of a power MOSFET transistor. The test
load is a 0.03uF capacitor in series with an 40Ω resistor. The
LED test frequency is 10.0kHz with a 50% duty cycle. The com-
bined IOH and IOL output load current duty factor is 0.6% at the
test frequency.
Figure 14 illustrates the relationship of the LED input drive
current and the device’s output voltage and sourcing and sink-
ing currents. The 0.03µF capacitor load represents the gate to
source capacitance of a very large power MOSFET transistor.
A single supply voltage of 20V is used in the evaluation.
Figure 15 shows the test schematic to evaluate the output volt-
age and sourcing and sinking capability of the device. The IOH
and IOL are measured at the peak of their respective current
pulses.
