Applications

General Description

The IXDD404 is comprised of two 4 Amp CMOS high speed

MOSFET drivers. Each output can source and sink 4 A of

peak current while producing voltage rise and fall times of less

than 15ns to drive the latest IXYS MOSFETS & IGBT's. The

input of the driver is compatible with TTL or CMOS and is 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 IXDD404. Improved speed

and drive capabilities are further enhanced by very low,

matched rise and fall times.

Additionally, each driver in the IXDD404 incorporates a unique

ability to disable the output under fault conditions. When a

logical low is forced into the Enable input of a driver, both of it's

final output stage MOSFETs (NMOS and PMOS) are turned

off. As a result, the respective output of the IXDD404 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 IXDD404 is available in the standard 8 pin P-DIP (PI),

SOIC-8 (SIA) and SOIC-16 (SIA-16) packages. For enhanced

thermal performance, the SOP-8 and SOP-16 are also avail-

able with an exposed grounded metal back package as the SI

and SI-16 respectively.
