IC revision1.3

Description

The AEM10941 is an integrated energy management circuitthat extracts DC power from up to 7-cell solar panels to si-multaneously store energy in a rechargeable element and sup-ply the system with two independent regulated voltages. TheAEM10941 allows to extend battery lifetime and ultimatelyeliminates the primary energy storage element in a large rangeof wireless applications, such as industrial monitoring, geoloca-tion, home automation, e-health monitoring and wireless sen-sor nodes.

Features

  • Ultra-low power start-up:
  • Cold start from 380 mV input voltage and 3 μW input power (typical)
  • Ultra-low power boost regulator:
  • Open-circuit voltage sensing for MPPT every 5 s
  • Configurable MPPT with 2-pin programming
  • Selectable Voc ratios of 70, 75, 85 or 90 %
  • Input voltage operation range from 50 mV to 5 V
  • MPPT voltage operation range from 50 mV to 5 V
  • Integrated 1.2/1.8 V LDO regulator:
