Space, mankind's reach into the universe has been a difficult and expensive venture. But a new era is dawning, and Intersil has developed a new way to advance this era of rapid innovation.
The space environment is harsh. The traditional space missions have required the integrated circuits survive for a long period of time in this environment. However, the mission perimeters are changing. Today, the innovation in space is increasingly being influenced by the private industry.
Fleets of hundreds of small satellites are being developed to create mega constellations for low earth orbit. This dramatically drives the need to reduce costs to maintain reasonable profitability. Intersil has developed a new line of products to provide these satellite fleets with a cost-effective radiation-tolerant solution.
Intersil is introducing a whole new radiation-tolerant plastic package portfolio to be able to address this emerging market.
The rad-tolerant plastic package family offers designers a reliable, cost-effective solution.
The benefit of this new radiation-tolerant plastic portfolio products is it really brings a solid balance between a cost-effective solution and a reliable solution that you could use confidently in a shorter mission life program.
Intersil's rad-tolerant plastic parts include the ISL71026M 3.3-volt controller area network transceiver, the ISL71444M 40-volt quad precision rail to rail input and output op am, and the ISL71001M point-of-load voltage regulator. These ICs deliver rad-tolerance performance at a much lower cost point.
Typically, when you're using a radiation hardened product, you're using it in a mission that tends to be over 15 years in length and also in a higher orbit where the radiation environment tends to be more harsh. For missions that are shorter in life and are lower in orbit, the radiation-tolerant plastic products are a good fit.
Intersil's cost-effective radiation-tolerant plastic ICs overcome the reliability issues and hidden costs of commercial off-the-shelf ICs, giving satellite manufacturers the confidence and mission success assurance to launch and operate mega constellations.
On the qualification side of things, we do an AEC-Q100 like qualification. For example, for new technologies, we do a life test or burn in up to 2,000 hours, temperature cycling up to 500 cycles, and moisture sensitivity tests.
Intersil's rad-tolerant plastic packaging flow leverages the company's more than 50 years of space-wide experience. developing rad-hard and rad-tolerant products for extremely harsh environments. And we look forward to continue to power the future of space.
