IXYS IXDF404PI 4 ampere dual low-side ultrafast mosfet driver Datasheet

IXDN404 / IXDI404 / IXDF404
4 Ampere Dual Low-Side Ultrafast MOSFET Drivers
Features
General Description
• Built using the advantages and compatibility
of CMOS and IXYS HDMOSTM processes
• Latch-Up Protected up to 0.5A
• High Peak Output Current: 4A Peak
• Wide Operating Range: 4.5V to 35V
• High Capacitive Load
Drive Capability: 1800pF in <15ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• Low Output Impedance
• Low Supply Current
• Two Drivers in Single Chip
The IXDN404/IXDI404/IXDF404 is comprised of two 4 Ampere
CMOS high speed MOSFET drivers. Each output can source
and sink 4A of peak current while producing voltage rise and
fall times of less than 15ns to drive the latest IXYS MOSFETs
and IGBT's. The input of the driver is compatible with TTL or
CMOS and is fully immune to latch up over the entire operating
range. A patent-pending circuit virtually eliminates CMOS
power supply cross conduction and current shoot-through.
Improved speed and drive capabilities are further enhanced by
very low, matched rise and fall times.

The IXDN404 is configured as a dual non-inverting gate driver,
the IXDI404 is a dual inverting gate driver, and the IXDF404 is a
dual inverting + non-inverting gate driver.
The IXDN404/IXDI404/IXDF404 family are available in the
standard 8 pin P-DIP (PI), SOIC-8 (SIA) and SOIC-16 (SIA-16)
packages. For enhanced thermal performance, the SOP-8 and
SOP-16 are also available in a package with an exposed
grounded metal back as the SI and SI-16 repectively.

Supply Bypassing, Grounding Practices And Output Lead inductance
GROUNDING
In order for the design to turn the load off properly, the IXDN404
must be able to drain this 2.5A of current into an adequate
grounding system. There are three paths for returning current
that need to be considered: Path #1 is between the IXDN404
and its load. Path #2 is between the IXDN404 and its power
supply. Path #3 is between the IXDN404 and whatever logic is
driving it. All three of these paths should be as low in resistance
and inductance as possible, and thus as short as practical. In
addition, every effort should be made to keep these three
ground paths distinctly separate. Otherwise, the returning
ground current from the load may develop a voltage that would
have a detrimental effect on the logic line driving the IXDN404.
When designing a circuit to drive a high speed MOSFET
utilizing the IXDN404/IXDI404/IXDF404, it is very important to
observe certain design criteria in order to optimize performance
of the driver. Particular attention needs to be paid to Supply
Bypassing, Grounding, and minimizing the Output Lead
Inductance.
Say, for example, the IXDN404 is being used to charge a
2500pF capacitive load from 0 to 25 volts in 25ns.
Using the formula: I= ∆V C / ∆t, where ∆V=25V C=2500pF &
∆t=25ns, one can determine that to charge 2500pF to 25 volts
in 25ns will take a constant current of 2.5A. (In reality, the
charging current won’t be constant and will peak somewhere
around 4A).
OUTPUT LEAD INDUCTANCE
Of equal importance to Supply Bypassing and Grounding are
issues related to the Output Lead Inductance. Every effort
should be made to keep the leads between the driver and its
load as short and wide as possible. If the driver must be placed
farther than 2” (5mm) from the load, then the output leads
should be treated as transmission lines. In this case, a twistedpair should be considered, and the return line of each twisted
pair should be placed as close as possible to the ground pin
SUPPLY BYPASSING
In order for the design to turn the load on properly, the IXDN404
must be able to draw this 2.5A of current from the power supply
in the 25ns. This means that there must be very low impedance
between the driver and the power supply. The most common
method of achieving this low impedance is to bypass the power
supply at the driver with a capacitance value that is a magnitude
larger than the load capacitance. Usually, this would be
achieved by placing two different types of bypassing capacitors,
with complementary impedance curves, very close to the driver
itself. (These capacitors should be carefully selected, low
inductance, low resistance, high-pulse current-service
capacitors). Lead lengths may radiate at high frequency due
to inductance, so care should be taken to keep the lengths of
the leads between these bypass capacitors and the IXDN404
to an absolute minimum.
of the driver, and connected directly to the ground terminal
of the load.
