Ordering Information

General Description

The IXDN430/IXDI430/IXDD430/IXDS430 are high speed high 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 voltages are 11.75V

for the IXD_430 parts and 8.5V for the IXD_430M parts. ULVO can be

set to either level in the IXDS430 with the UNSEL input line. 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-voltage transient.

The IXDN430 is configured as a noninverting gate driver, and the IXDI430

is an inverting gate driver. The IXDS430 can be configured either as a

noninverting or inverting driver. The IXD_430 are available 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.
