Quad Isolated Precision
Gate Driver, 0.1 A Output
ADuM1420
FEATURES
GENERAL DESCRIPTION
Quad outputs isolated from input and each other
Input-to-output differential: ±700 V peak
Output-to-output differential: ±700 V peak
0.1 A peak output current
High frequency operation: 5 MHz maximum
High common-mode transient immunity: >75 kV/μs
High temperature operation: 105°C
Wide body, 28-lead SOIC
The ADuM14201 is a quad isolated gate driver that employs
Analog Devices, Inc. iCoupler® technology to provide
independent and isolated high-side and low-side outputs.
In comparison to gate drivers employing high voltage level
translation methodologies, the ADuM1420 offers the benefit of
true, galvanic isolation between the input and each of the four
outputs. Each output can be operated up to ±700 V peak relative to
the input, thereby supporting low-side switching to negative
voltages. The differential voltage between any two outputs can
be as high as 700 V peak.

APPLICATION INFORMATION
The sinusoidal component (at a given frequency) is given by
COMMON-MODE TRANSIENT IMMUNITY
VCM, sinusoidal = V0sin(2πft)
In general, common-mode transients consist of linear and
sinusoidal components. The linear component of a commonmode transient is given by
where:
V0 is the magnitude of the sinusoidal.
f is the frequency of the sinusoidal.
VCM, linear = (ΔV/Δt) t
where ΔV/Δt is the slope of the transient shown in Figure 8 and
Figure 9.

The ability of the ADuM1420 to operate correctly in the

and is the maximum sinusoidal transient magnitude (2πf V0)
that the ADuM1420 can tolerate without an operational error.
Values for immunity against sinusoidal transients are not included

TRANSIENT IMMUNITY (kV/µs)
The ability of the ADuM1420 to operate correctly in the
presence of linear transients is characterized by the data in
Figure 10. The data is based on design simulation and is the
maximum linear transient magnitude that the ADuM1420 can
tolerate without an operational error. This data shows a higher
level of robustness than what is shown in Table 5 because the
transient immunity values obtained in Table 5 use measured
data and apply allowances for measurement error and margin.

POWER-UP/POWER-DOWN CONSIDERATIONS
Given that the ADuM1420 has separate supplies on either side
of the isolation barrier for each channel, the power-up/powerdown characteristics relative to each supply voltage need to be
considered individually.
As shown in Table 7, when VDD1 input power is off, the ADuM1420
outputs take on a default low logic state. As the VDD1 supply is
increased/decreased, the output of each channel transitions
from/to a logic low to/from the state matching its respective
input (see Figure 13 and Figure 14).
OUTPUT
DATA
When VDD1 crosses the threshold for activating the refresh
function (approximately 2.5 V), there can be a delay of up to
2 μs before the output is updated to the correct state, depending
on the timing of the next refresh pulse. When VDD1 is reduced
from an on state to below the 2.0 V threshold, there can be a
delay of up to 5 μs before the output takes on its default low state.
In addition, during power-up/power-down, there is a range of
VDD1 values within which erroneous outputs can occur if the
input data either is a logic high or is in transition between logic
states. This range is between 2.5 V and 2.7 V. The recommended
practice is to set all the input logic levels to low during power-up/
power-down.
