Overview

This power management solution delivering 900mA @3.6V from various battery types for smart flow metering applications (residential gas and water meters). TIDA-00676 includes an ETSI Cat. 1 receiver capable RF subsystem for wM-Bus @ 169 MHz with up to +30 dBm transmit power meets all technical requirements for 169MHz RF links in Italy and France. Power management and RF sub-systems can be equally well used in data collectors and other end nodes (E-meter or In-Home Display) with wM-Bus@ 169 MHz links.

Features
  • 360-nA Iq Step-Down Converter charges a SuperCap from multiple battery chemistries
  • Boost device supplies the 900mA current to a +30dBm Power Amplifier(PA)
  • ETSI Cat. 1 Receiver capable wM-Bus subsystem @ 169MHz with up to +30dBm transmit power and 55dB dynamic range
  • Ultra-low power FRAM MCU with rotation detection hardware and LCD controller
  • SRF7 configurations files for Receiving wM-Bus packets in all N-modes
  • Includes firmware in source code,  SRF7 Studio GUI configuration files and User's Guide
