24SW 24 Channel MOSFET Driver LDX_IN LDX_OUT SS_CMD_X 1 of 24 Switches Memory Logic Diagram FEATURES: 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. 24 independently switchable power FETs Low equivalent on resistance (200 mΩ typ) 2A switching current per channel No derating required to 90° C Total dose hardness: depending upon space mission in RAD-PAK® • Package: 176-pin quad flat pack 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 200mΩ. 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 Maxwell Technologies self-defined Class K. 01.10.05 Rev 2 (858) 503-3300 - Fax: (858) 503-3301 - www.maxwell.com All data sheets are subject to change without notice 1 ©2005 Maxwell Technologies.
