APPEB1012 – Solar Cell charging with PMIC

  • $170.00


The APPEB1012 is designed to aid the development of energy harvesting applications with a supercapacitor, particularly solar energy harvesting, using a PMIC to achieve a highly efficient, regulated dual-output supply using a supercapacitor as the high-power energy storage element.

A cold-start circuit allows the board to start operation with a discharged supercapacitor with an input voltage as low as 380 mV and input power of just 3 µW. The board incorporates a maximum power point tracking (MPPT) switch mode power management IC (PMIC),

Main Features

  • PCB supports entire range of CAP-XX supercapacitors (Less than or equal to 100F)
  • Supports both single and dual cell devices with integrated active cell balancing
  • Ultra-low power boost regulator, e-peas AEM10941 with:
    • Open-circuit voltage sensing for MPPT every 5s
    • Configurable MPPT with 2-pin programming
    • Selectable Vppt/Voc ratio of 70%, 75%, 85%, 90%
    • Vin operation from 50mV to 4.5V
    • Configurable cell voltage control
  • Charge voltage regulation configurable via headers
  • Eight inbuilt operation modes including user customisable mode for selectable supercapacitor voltage
  • Integrated dual output LDO regulators:
    • Low voltage LDO of 1.2 / 1.8 V with up to 20 mA load current
    • High voltage LDO of 1.8 – 4.2 V up to 80 mA load current with 300 mV drop out
  • Output voltage control configurable via a jumper link:
    • PMIC controlled output with user customisable voltage thresholds
    • Direct connection between supercapacitor and the output
  • Multiple test points
  • Test points for input voltage and supercapacitor voltage measurement
  • Includes 1Ω resistors for input and output current sensing

Note: The APPEB1012 Evaluation Board is made to order. Please allow 2-3 weeks for delivery. If there is a significant delay shipping your order, CAP-XX will notify you via email or telephone.
