The IXDD408 is a high speed high current gate driver specifically designed to drive the largest MOSFETs and IGBTs to their minimum switching time and maximum practical frequency limits. The IXDD480 can source and sink 8A of peak current while producing voltage rise and fall times of less than 30ns. 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 shootthrough is virtually eliminated in the IXDD408. Its features and wide safety margin in operating voltage and power make the IXDD408 unmatched in performance and value.
The IXDD408 incorporates 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 IXDD408 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 IXDD408 is available in the standard 8-pin P-DIP (PI), SOP-8 (SI), 5-pin TO-220 (CI) and in the TO-263 (YI) surface-mount package.
