DESCRIPTION:
Maxwell Technologies 24SW multi-chip module (MCM) 24 channel MOSFET driver uses Maxwell Technologies' patented radiation-hardened RAD-PAK® MCM packaging technology. The 24SW is a radiation hardened MOSFET driver for space applications. The 24SW incorporates twenty-four independent pchannel MOSFETs, along with interface components, that can switch up to 2A per channel. The RDS-ON of the MOSFET is typically less than 200m. Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit 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 Class K.
