Intersil Corporation has introduced ISL72813SEH radiation hardened 32-channel driver with integrated decoder that reduces the size, weight and power (SWaP) of satellite command and telemetry systems. The high current driver integrates the decoder, level shifter and driver array in a single monolithic IC which allows satellite manufacturers to increase system capacity and reduce solution size by up to 50%. The device offers a 4x higher density channel count compared to the nearest competitor, and the integrated level shifter eliminates several peripheral components.
The ISL72813SEH driver leverages Intersil's proprietary silicon on insulator process, which provides single-event latch-up (SEL) robustness in heavy ion environments. The driver's integrated decoder interfaces directly to the general purpose I/Os of FPGAs and CPUs in the satellite's flight computer. The device addresses latching relay and solenoid commanding for most satellite control functions, including redundancy management, mechanism drive enables, propulsion component relays and enables, battery management, and payload switch control.
"The ISL72813SEH gives our space customers like Orbital ATK the integration and performance they need for cutting edge military and commercial space applications," said Philip Chesley, senior vice president of Precision Products at Intersil. "The mass and power savings our rad hard devices deliver play a critical role in Orbital ATK's next generation satellites."
Key features and specifications:
Complete satellite command and telemetry signal processing solution can be developed when the ISL72813SEH is combined with the following ICs:
The ISL72813SEH driver is available now in a 44-lead ceramic lead-less chip carrier (CLCC) package. An evaluation board, SEE and total dose testing reports are also are available.
