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).
