General Description
The IXDD414 is a high speed high current gate driver
specifically designed to drive the largest MOSFETs and
IGBTs to their minimum switching time and maximum
practical frequency limits. The IXDD414 can source and
sink 14A of peak current while producing voltage rise and
fall times of less than 30ns. 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 IXDD414. Its features
and wide safety margin in operating voltage and power
make the IXDD414 unmatched in performance and value.
The IXDD414 incorporates a unique ability to disable the
output under fault conditions. When a logical low is
forced into the Enable input, both final output stage
MOSFETs (NMOS and PMOS) are turned off. As a
result, the output of the IXDD414 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 tran-
sient.
The IXDD414 is available in the standard 8-pin P-DIP (PI),
5-pin TO-220 (CI) and in the TO-263 (YI) surface-mount
package.
