Wide Temperature Rad-Hard ASIC for Process Control of a Fuel Cell System, Phase II

Completed Technology Project

Project Introduction

Wide Temperature Rad-Hard ASIC for Process Control of a Fuel Cell System, Phase II
Ridgetop Group developed a top-level design of a rad-hard application-specific integrated circuit (ASIC) for spacecraft power management that is functional over a temperature range of -180 to +130 oC. This ASIC is intended to work in conjunction with a fuel cell power system and battery backup to provide uninterrupted power to critical modules in space. Ridgetop has designed a novel integrated circuit for the power management of space systems. This design combines custom circuit modules with silicon-proven IP to create a system-on-chip solution. This application will be a single monolithic circuit designed for fabrication on the IBM 5AM SiGe process. The significance of this innovation is a single reliable component (ASIC) that will meet platform requirements for high voltage, wide operating temperature range, and radiation tolerance (minimum 100 krads total ionizing dose (TID), and 100 MeVcm2/mg single-event latchup (SEL)). Ridgetop has been working with a prime contractor to identify and flow-down mission requirements for the power management ASIC. During Phase 2, a final prototype unit will be fabricated to these specifications, and units will be packaged, tested, and silicon validation results will be produced. Estimated TRL at beginning and end of Phase 2 contract: Begin: 3, End: 6 More »
