E-peas AEM20940 Quick Start Manual page 2

STEP 1: AEM20940 Configuration
• MPPT ratio:
• Storage Element voltages protection:
• BAL option:
storage
• PRIM option:
battery is connected. Define the lower limit voltage on the primary battery using
R7 and R8 (2.2V by default with the jumper and 0R R7 mounted)
• ZMPP resistors footprint
• LDOs Outputs Voltages:
• External coldstart circuit to enable coldstart at 60mV – 150 µW
STEP 2: Connect the Storage Element (and the Primary Battery)
STEP 3: Connect the Load(s) to HVOUT / LVOUT
STEP 4: Connect the Thermo-Electric Generator
• Internal Boost efficiency Vs. input voltage:
STEP 5: Check the Status
SELMPP[0] – SELMPP[1]
Select "ToCn" for dual-cells supercapcacitor and "GND" for any other
Connect both jumpers "NoPRIM" or remove them if a primary
• 100 kΩ ≤ RP ≤ 500 kΩ

• R7 = (
* RP) / 2.2 V
4
• R9 = RP – R7
ENHV (HVOUT) – ENLV (LVOUT)
