General Description

TheIXDN430/IXDI430/IXDD430/IXDS430arehighspeedhigh

current gate drivers specifically designed to drive MOSFETs

and IGBTs to their minimum switching time and maximum

practical frequency limits. The IXD_430 can source and sink

30A 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 all

configurations. Their features and wide safety margin in

operating voltage and power make the drivers unmatched in

performance and value.

The IXD_430 incorporates a unique ability to disable the output

under fault conditions. The standard undervoltage lockout is at

12.5V which can also be set to 8.5V in the IXDS430SI. When a

logical low is forced into the Enable inputs, both final output

stage MOSFETs (NMOS and PMOS) are turned off. As a

result, the output of the IXDD430 enters a tristate mode and

enables a Soft Turn-Off of the MOSFET when a short circuit is

detected. This helps prevent damage that could occur to the

MOSFET if it were to be switched off abruptly due to a dv/dt

over-voltagetransient.

The IXDN430 is configured as a noninverting gate driver, and the

IXDI430 is an inverting gate driver. The IXDS430 can be configured

eitherasanoninvertingorinvertingdriver.TheIXD_430areavailable

in the standard 28-pin SIOC (SI-CT), 5-pin TO-220 (CI), and in the

TO-263 (YI) surface mount packages. CT or 'Cool Tab' for the 28-

pin SOIC package refers to the backside metal heatsink tab.
