Radiation-Hardened Mixed-Signal ICs

Reduced Board Space, Reduced Weight and Increased Reliability for Your Space Designs

Building on nearly six decades of innovation and expertise in space electronics, our portfolio of radiation-hardened Integrated Circuits (ICs) continues to expand with the inclusion of advanced mixed-signal solutions. Each of these products integrates commonly used satellite functions into a single, space-saving device. This results in a simplified solution that can meet demanding weight and space requirements while increasing reliability in your designs.

Our Solutions Offer:

  • High performance in satellites of various types operating in a range of orbits
  • Radiation-hardened by design
  • Significant reduction in BOM IC count for increased reliability, reduced board space and reduced weight
  • Designs derived from development expertise with circuit elements that have over 15 years of flight heritage
  • Custom options for your specific application needs

How Can You Use Our Solutions in Your Design?

Reduced Board Space Reduced Weight Reduced Reliability

Position Sensing/Motor Control

Satellites and other space instrumentation systems contain many motor control applications. These applications include robotics, multi-axis pointing mechanisms for antennas and laser terminals, solar panel positioning and precise motion control of mirrors and lenses. Our LX7720 power driver with rotation and position sensing provides motor driver and linear actuator servo control to Brushless Direct Current (BLDC) motors, Permanent-Magnet Synchronous Motors (PMSMs) and other types of motors.

Featured Product:

  • LX7720 Spacecraft Motor Controller with Position Sensing

Power Protection and Management

Managing power to improve efficiency and save precious stored energy in satellite systems is key. Protecting power sources and loads from damage is also essential. We offer the following reliable mixed-signal solutions to help you achieve both of these design requirements.

Featured Products:

Telemetry

Satellite payload instruments need to collect huge amounts of telemetry data to ensure safe and reliable satellite operation. In addition to monitoring the health of the satellite, telemetry also detects faults, helps in the isolation and recovery of the satellite from the ground station if needed, and allows the satellite to autonomously control payload instrument loading. This aids in monitoring power consumption and thermal dissipation, which is critical to avoid overloading and to preserve the life of the satellite.
