Versatile satellite health monitoring and control platform reference design with < 1% accuracy


Design files


This reference design features a highly modular design for radiation-hardened satellite telemetry systems that utilizes the versatility of LMP7704-SP to accurately monitor temperature, voltage and current to provide feedback to the host board. It also provides controlled analog outputs to provide protection and optimal efficiency. The majority of space applications require monitoring of these three key measurables in multiple sub-systems of the satellite.

  • Nine analog inputs (1% accuracy)
  • Three analog outputs
  • External ADC or MCU integrated ADC options
