IXYS IXDF502SIAT/R 2 ampere dual low-side ultrafast mosfet driver Datasheet

IXDF502 / IXDI502 / IXDN502
2 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 2 Amps
• High 2A Peak Output Current
• Wide Operating Range: 4.5V to 30V
• -55°C to +125°C Extended Operating
Temperature
• High Capacitive Load
Drive Capability: 1000pF in <10ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• Low Output Impedance
• Low Supply Current
• Two Drivers in Single Chip
The IXDF502, IXDI502 and IXDN502 each consist of two 2Amp CMOS high speed MOSFET Gate Drivers for driving
the latest IXYS MOSFETs & IGBTs. Each of the Dual
Outputs can source and sink 2 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 quick & 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_502, 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_502 to charge a 1500pF
capacitive load from 0 to 25 volts in 25ns.
Using the formula: I = C ∆V/∆t, where ∆V=25V C=1500pF &
∆t=25ns, we can determine that to charge 1500pF to 25 volts in
25ns will take a constant current of 1.5A. (In reality, the charging
current won’t be constant, and will peak somewhere around 2A).
SUPPLY BYPASSING
In order for our design to turn the load on properly, the IXD_502
must be able to draw this 1.5A 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 currentservice 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_502 to an
absolute minimum.
GROUNDING
In order for the design to turn the load off properly, the IXD_502
must be able to drain this 1.5A 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_502 and its
load. Path #2 is between the IXD_502 and its power supply. Path
#3 is between the IXD_502 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_502.
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 twisted-pair 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.
