• High Peak Output Current: 9A Peak
• Operates from 4.5V to 35V
• -55° C to 125° C Extended Operating Temperature
Standard
• Ability to Disable Output under Faults
• High Capacitive Load
Drive Capability: 2500pF in <15ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• Low Output Impedance
• Low Supply Current
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 IXDN409 is configured as a non-inverting gate driver, and
the IXDI409 is an inverting gate driver.
The IXDD409/IXDI409/IXDN409 are available in the standard 8-pin
P-DIP (PI), SOIC-8 (SI), 5-pin TO-220 (CI) and in the TO-263 (YI)
surface-mount packages.
