FOD3180 — 2A Output Current, High Speed MOSFET Gate Driver Optocoupler
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. Maximum pulse width = 1ms, maximum duty cycle = 20%.
8. 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.
9. PWD is defined as | t
PHL
– t
PLH
| for any given device.
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.
