Maxwell Technologies 24SW multi-chip module (MCM)
24 channel MOSFET driver uses Maxwell Technologies'
patented radiation-hardened R
AD
-P
AK
MCM packaging
technology. The 24SW is a radiation hardened MOSFET
driver for space applications.
The 24SW incorporates twenty-four independent p-
channel MOSFETs, along with interface components,
that can switch up to 2A per channel. The R
DS-ON
of the
MOSFET is typically less than 200m
.
Maxwell Technologies' patented R

-P
AK
packaging
technology incorporates radiation shielding in the micro-
circuit package. It eliminates the need for box shielding
while improving the TID performance in most space
environments. This product is available with screening
up to Maxwell Technologies self-defined Class K.
