Single-Chip Rad Hard 32-Channel Driver with Integrated Decoder for Satellite Applications Announced by Intersil

By Intersil February 28, 2017

Intersil Corporation, a leading provider of innovative power management and precision analog solutions, has introduced a radiation hardened 32-channel driver. It carries an 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.

Moving on to the performance, the driver 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 reduce the overhead voltage required to drive the load, thereby eliminating a major customer concern. The driver’s power efficiency and high integration reduce the amount of circuitry required on the bus, allowing customers to add more spacecraft functionality and processing power.
 
Key Features and Specifications of ISL72813SEH
 
•        Acceptance tested to 50krad(Si) LDR, wafer-by-wafer
•        Integrated 5-bit to 32-channel decoder and level shifting circuit
•        High collector current outputs to 600mA
•        Low VCE saturation of 1.5V with IC of 530mA
•        High voltage outputs up to -40V
•        VCC supply range of 3V to 5.5V
•        Extended operating temperature range of -55°C to +125°C
•        HDR radiation tolerance of 100krad(Si) and LDR of 50krad(Si)
•        SEB LETTH (VCE = 33V) immune up to 86.4MeV•cm2/mg
 
“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.”
 
The ISL72813SEH can be combined with the following ICs to create a complete satellite command and telemetry signal processing solution with superior rad hard performance:
 
 ISL71841SEH 32-channel 30V multiplexer,
 ISL70444SEH, ISL70244SEH, ISL70419SEH and ISL70219ASEH precision op amps,
 ISL71090SEH and ISL71091SEH low-noise voltage references,
 ISL70517SEH and ISL70617SEH differential input in-amps,
 ISL71590SEH temperature sensor, 
 ISL72026SEH CAN transceivers.
 
Availability
 
The ISL72813SEH high current driver is available now in a 44-lead ceramic lead-less chip carrier (CLCC) package. An evaluation board is available to evaluate device features and performance.
