24 Channel MOSFET Driver
©2005 Maxwell Technologies. All rights reserved.
01.10.05 Rev 2
FEATURES:
- 24 independently switchable power FETs Low equivalent on resistance (200 m Ω typ) 2A switching current per channel No derating required to 90 Total dose hardness: depending upon space mission in RAD-PAK® Package: 176-pin quad flat pack DESCRIPTION: Maxwell Technologies 24SW multi-chip module (MCM) 24 channel MOSFET driver uses Maxwell Technologies’ patented radiation-hardened R AD-PAK® 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 200mΩ. Maxwell Technologies' patented R AD-PAK® 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.
