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
transient.
The IXDD414 is available in the standard 8-pin P-DIP (PI),
14-pin SOIC (SI), 5-pin TO-220 (CI) and in the TO-263 (YI)
surface-mount package.
