General Description
The IXDD409/IXDI409/IXDN409 are high speed high current
gate drivers specifically designed to drive the largest
MOSFETs and IGBTs to their minimum switching time and
maximum practical frequency limits. The IXDD409/IXDI409/
IXDN409 can source and sink 9A of peak current while
producing voltage rise and fall times of less than 30ns. The
input of the drivers are compatible with TTL or CMOS and are
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 IXDD409/
IXDI409/IXDN409. Their features and wide safety margin in
operating voltage and power make the drivers unmatched in
performance and value.
The IXDD409 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 IXDD409 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 IXDI409 is an inverting gate driver.
The IXDD409/IXDI409/IXDN409 are available in the standard 8-
pin P-DIP (PI), SOP-8 (SI), 5-pin TO-220 (CI) and in the TO-263
(YI) surface-mount packages.
The IXDN409 is configured as a non-inverting gate driver, and
