General Description
The IXDD514 and IXDE514 are high speed high current gate
drivers specifically designed to drive the largest IXYS
MOSFETs & IGBTs to their minimum switching time and
maximum parctical frequency limits. The IXDD514 and
IXDE514 can source and sink 14 Amps of Peak Current
while producing voltage rise and fall times of less than
30ns. The inputs of the Drivers are compatible with TTL or
CMOS and are virtually immune to latch up over the entire
operating range! Patented* design innovations eliminate
cross conduction and current "shoot-through". Improved
speed and drive capabilities are further enhanced by very
quick & matched rise and fall times.
The IXDD514 and IXDE514 incorporate 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 IXDD514 or IXDE514 enters a tristate
mode and achieves a Soft Turn-Off of the MOSFET/IGBT
when a short circuit is detected. This helps prevent dam-
age that could occur to the MOSFET/IGBT if it were to be
switched off abruptly due to a dv/dt over-voltage transient.
The IXDD514 and IXDE514 are each available in the 8-Pin
P-DIP (PI) package, the 8-Pin SOIC (SIA) package, and the
6-Lead DFN (D1) package, (which occupies less than 65%
of the board area of the 8-Pin SOIC).
