Footprint & Symbol: Available in the datasheet

1. 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

2. STEP 2: Connect the storage element (and the primary battery)

3. STEP 3: Connect the Load(s) to HVOUT / LVOUT

4. STEP 4: Connect the Harvester
