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.
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.
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.
We offer custom integrated circuit design and manufacturing of analog mixed-signal solutions for your unique space system needs. Our experienced team has been developing radiation-hardened designs for many years and has flight heritage in multiple satellite platforms. We will work with you throughout all stages of your design and production of your project.
Our expertise includes radiation testing, analysis and reporting for TID, SEL/SEU, ELDRS and neutron exposures and adherence to standards and certifications such as AS9100, ISO9001, MIL-PRF-38535 and QML.
The LX7730-DB allows you to evaluate key functions when using a LX7730 and an RTG4™ FPGA. It plugs directly into an RTG4 FPGA Development Kit via FMC connectors.
The LX7720-DB allows you to evaluate key functions when developing a LX7720-based motor drive system using an MCU system controller or an FPGA. It plugs directly into an RTG4 FPGA Development Kit via FMC connectors. It also connects to the SAMRH71F20-EK Evaluation Kit and other FPGA development platforms using an included 40-pin header.
The LX7730-EVB allows you to exercise LX7730 features when coupled with a USB-to-serial interface. Application software is provided, and the board comes with a cable assembly.
This video demonstrates using the LX7720 Rad Hard Motor Control IC with the SAMRH71 Rad Hard Arm MPU for satellite motor control and position sensing applications. Key features of each component are given along with a description of the evaluation system using the LX7720-DB daughter board with the SAMRH71F20-EK evaluation kit.
