DD404SIA

Product Summary

The DD404SIA 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 DD404SIA. Improved speed and drive capabilities are further enhanced by very low, matched rise and fall times.
Additionally, each driver in the DD404SIA 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 DD404SIA 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 DD404SIA is available in the standard 8 pin P-DIP (PI), SOP-8 (SI -with metal tab), SOP-8 (SIA -without metal tab) and SOP-16 (SI-16) packages.
