Key Document


When designing battery-powered applications, ultra-low power consumption is the key factor in extending the lifetime of a system. Long-running designs must not waste the energy they are provided. This TI design highlights the usage of TMR sensor and Extended Scan Interface (ESI) to archive ultra-low power
rotation detection for flow meter application. This design uses the evaluation kit EVM430-FR6989 and the custom TMR sensor board for testing.

  • Showcase of the daughter TMR sensor board for EVM430-FR6989
  • Showcase of rotation detection using TMR sensors
  • Platform support ultra-low power design using TI's proprietary Extended Scan Interface (ESI)
  • This TI design is tested and includes firmware,  and Getting Started guide.
