STEP 1: AEM00941 configuration
- Source level: Use the potentiometer or resistors R9 and R10 in combination of the source range functionality to define the harvesting voltage.
- RS = R9 + R10
- 100 kΩ ≤ RS ≤ 500 kΩ
- R9 = * RS) / 2.2 V
- R10 = RS – R9
-
STEP 2: Connect the storage element (and the primary battery)
-
STEP 3: Connect the Load(s) to HVOUT / LVOUT
-
STEP 4: Connect the Harvester
