Description
The FOD3180 is a 2A Output Current, High Speed
MOSFET Gate Drive Optocoupler. It consists of a
aluminium gallium arsenide (AlGaAs) light emitting diode
optically coupled to a CMOS detector with PMOS and
NMOS output power transistors integrated circuit power
stage. It is ideally suited for high frequency driving of
power MOSFETs used in Plasma Display Panels
(PDPs), motor control inverter 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.

Absolute Maximum Ratings
(T
A
= 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
1. Derate linearly above +70°C free air temperature at a rate of 0.3mA/°C.
2. The output currents I
OH
and I
OL
are specified with a capacitive current limited load = (3 x 0.01µF) + 0.5Ω,
frequency = 8kHz, 50% DF.
3. The output currents I
OH
and I
OL
are specified with a capacitive current limited load = (3 x 0.01µF) + 8.5Ω,
frequency = 8kHz, 50% DF.
4. Derate linearly above +87°C, free air temperature at the rate of 0.77mW/°C. Refer to Figure 12.
5. No derating required across operating temperature range.
6. In this test, V
OH
is measured with a dc load current of 100mA. When driving capacitive load V
OH
will approach V
CC
as I
OH
approaches zero amps.
7.
8.
Maximum pulse width = 1ms, maximum duty cycle = 20%.
t
PHL
propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the
falling edge of the V
O
signal. t
PLH
propagation delay is measured from the 50% level on the rising edge of the input
pulse to the 50% level of the rising edge of the V
O
signal.
PWD is defined as | t
PHL
– t
PLH
| for any given device.
9.
10. The difference between t
PHL
and t
PLH
between any two FOD3180 parts under same test conditions.
11. Pin 1 and 4 need to be connected to LED common.
12. Common mode transient immunity in the high state is the maximum tolerable dV
CM
/dt of the common mode pulse
V
CM
to assure that the output will remain in the high state (i.e. V
O
> 10.0V).
13. Common mode transient immunity in a low state is the maximum tolerable dV
CM
/dt of the common mode pulse,
V
CM
, to assure that the output will remain in a low state (i.e. V
O
< 1.0V).
14. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000Vrms,
60Hz for 1 second (leakage detection current limit I
I-O
< 5µA).
15. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted
together.
