IXYS IXDF504PI 4 ampere dual low-side ultrafast mosfet driver Datasheet

IXDF504 / IXDI504 / IXDN504
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 4 Amps
• High Peak Output Current: 4A Peak
• Wide Operating Range: 4.5V to 30V
• -55°C to +125°C Extended Operating
Temperature
• 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 IXDF504, IXDI504 and IXDN504 each consist of two 4Amp CMOS high speed MOSFET Gate Drivers for driving
the latest IXYS MOSFETs & IGBTs. Each of the outputs
can source and sink 4 Amps of Peak Current while producing voltage rise and fall times of less than 15ns. The input
of each driver is TTL or CMOS compatible and is virtually
immune to latch up. Patented* design innovations eliminate
cross conduction and current "shoot-through". Improved
speed and drive capabilities are further enhanced by very
fast, matched rise and fall times.

Notes:
1. Operating the device beyond the parameters listed as “Absolute Maximum Ratings” may cause permanent
damage to the device. Exposure to absolute maximum rated conditions for extended periods may affect device
reliability.
2. The device is not intended to be operated outside of the Operating Ratings.
3. Electrical Characteristics provided are associated with the stated Test Conditions.
4. Typical values are presented in order to communicate how the device is expected to perform, but not necessarily
to highlight any specific performance limits within which the device is guaranteed to function.
* The following notes are meant to define the conditions for the θJ-A, θJ-C and θJ-S values:
1) The θJ-A (typ) is defined as junction to ambient. The θJ-A of the standard single die 8-Lead PDIP and 8-Lead SOIC are dominated by the
resistance of the package, and the IXD_5XX are typical. The values for these packages are natural convection values with vertical boards
and the values would be lower with forced convection. For the 6-Lead DFN package, the θJ-A value supposes the DFN package is soldered
on a PCB. The θJ-A (typ) is 200 °C/W with no special provisions on the PCB, but because the center pad provides a low thermal resistance
to the die, it is easy to reduce the θJ-A by adding connected copper pads or traces on the PCB. These can reduce the θJ-A (typ) to 125 °C/W
easily, and potentially even lower. The θJ-A for DFN on PCB without heatsink or thermal management will vary significantly with size,
construction, layout, materials, etc. This typical range tells the user what he is likely to get if he does no thermal management.
2) θJ-C (max) is defined as juction to case, where case is the large pad on the back of the DFN package. The θJ-C values are generally not
published for the PDIP and SOIC packages. The θJ-C for the DFN packages are important to show the low thermal resistance from junction to
the die attach pad on the back of the DFN, -- and a guardband has been added to be safe.
3) The θJ-S (typ) is defined as junction to heatsink, where the DFN package is soldered to a thermal substrate that is mounted on a heatsink.
The value must be typical because there are a variety of thermal substrates. This value was calculated based on easily available IMS in the
U.S. or Europe, and not a premium Japanese IMS. A 4 mil dialectric with a thermal conductivity of 2.2W/mC was assumed. The result was
given as typical, and indicates what a user would expect on a typical IMS substrate, and shows the potential low thermal resistance for the
DFN package.

Supply Bypassing, Grounding Practices And Output Lead inductance
When designing a circuit to drive a high speed MOSFET
utilizing the IXD_504, 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, we are using the IXD_504 to charge a 2500pF
capacitive load from 0 to 25 volts in 25ns.
Using the formula: IC = C (∆V/∆t), where ∆V=25V C=2500pF &
∆t=25ns, we 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).
SUPPLY BYPASSING
In order for our design to turn the load on properly, the IXD_504
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 an order of
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 and should have low inductance, low resistance and
high-pulse current-service ratings). 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 IXD_504 to an absolute minimum.
GROUNDING
In order for the design to turn the load off properly, the IXD_504
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 IXD_504
and its load. Path #2 is between the IXD_504 and its power
supply. Path #3 is between the IXD_504 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 IXD_504.
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 0.2” (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
of the driver, and connected directly to the ground terminal of the
load.
