MILPITAS, Calif., Feb. 27, 2017 /PRNewswire/ -- Intersil
Corporation (NASDAQ: ISIL), a leading provider of innovative power
management and precision analog solutions, today introduced a
radiation hardened 32-channel driver with integrated decoder that
reduces the size, weight and power (SWaP) of satellite command and
telemetry systems. The ISL72813SEH is the industry's first high
current driver to integrate the decoder, level shifter and driver
array in a single monolithic IC, allowing satellite manufacturers
to significantly 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, dramatically reducing
pin count compared to competitive 1-input to 1-output driver
arrays. Each of the device's 32-channels of common-emitter
open-collector driver outputs can generate pulses of up to 42V and
600mA. The ISL72813SEH 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's low VCE saturation
levels eliminate a major customer concern by reducing the overhead
voltage required to drive the load. The driver's power efficiency
and high integration reduces the amount of circuitry required on
the bus, allowing customers to add more spacecraft functionality
and processing power.
"Intersil listened carefully to our technical requirements and
crafted a solution that enabled us to reduce the size of a critical
subsystem's by half while also reducing mass, cost and power," said
Joanne Woestman, senior director of
strategic sourcing at Orbital ATK Space Systems Group.
"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."
