IXDD404
4 Amp Dual Low-Side Ultrafast MOSFET Driver
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
• Ability to Disable Output under Faults
• High Capacitive Load
Drive Capability: 1800pF in <15ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• LowOutputImpedance
• LowSupplyCurrent
• Two identical drivers in single chip
The IXDD404 is comprised of two 4 Amp CMOS high speed
MOSFET drivers. Each output can source and sink 4 A of
peak current while producing voltage rise and fall times of less
than 15ns to drive the latest IXYS MOSFETS & 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. Designed
with small internal delays, cross conduction/current shoot-
throughisvirtuallyeliminatedintheIXDD404.Improvedspeed
anddrivecapabilitiesarefurtherenhancedbyverylow,
matched rise and fall times.
Additionally,eachdriverintheIXDD404incorporatesaunique
ability to disable the output under fault conditions. When a
logical low is forced into the Enable input of a driver, both of it's
final output stage MOSFETs (NMOS and PMOS) are turned
off. As a result, the respective output of the IXDD404 enters a
tristate mode and achieves a Soft Turn-Off of the MOSFET/
IGBT when a short circuit is detected. This helps prevent
damage that could occur to the MOSFET/IGBT if it were to be
switchedoffabruptlyduetoadv/dtover-voltagetransient.
Applications
• DrivingMOSFETsandIGBTs
• Limiting di/dt under Short Circuit

The IXDD404 is available in the standard 8 pin P-DIP (PI),
SOIC-8(SIA)andSOIC-16(SIA-16)packages.Forenhanced
thermal performance, the SOIC-8 and SOIC-16 are also avail-
able with an exposed grounded metal back package as the SI
andSI-16respectively.
