General Description
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-
through is virtually eliminated in the IXDD404. Improved speed
and drive capabilities are further enhanced by very low,
matched rise and fall times.
Additionally, each driver in the IXDD404 incorporates a unique
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
switched off abruptly due to a dv/dt over-voltage transient.
The IXDD404 is available in the standard 8 pin P-DIP (PI),
SOP-8 (SI) and SOP-16 (SI-16) packages.
