Product Information
Specifications:
- Model: AEM10941
- Version: EVK
- PCB Support: Yes
- BOM: Available around the AEM10941
- Footprint & Symbol: Available in the datasheet
Product Usage Instructions
Step 1: Configure the AEM10941
Adjust the voltage on the primary battery using resistors R7 and
R8. The recommended values are R7 = 4 and R8 = 2.2.
Step 2: Connect the Storage Element
Connect the storage element along with the primary battery.
Step 3: Connect the Load(s)
Connect the load(s) to HVOUT / LVOUT.
Step 4: Connect the Harvester
Connect the harvester to complete the setup.
Step 5: Check the Status
Ensure all connections are secure and check the status of the
AEM10941 system.
FAQ
Q: How do I know if my AEM10941 is functioning correctly?
A: You can check the status indicators on the device or measure
the output voltage to verify proper functionality.

STEP 1: Configure the AEM10941
· MPPT ratio: SELMPP[1:0] · Storage Element voltages protection: CFG[2:0]
· BAL option: Select “ToCn” to use the balancing or “GND” to disable it
· PRIM option: Connect both headers “NoPRIM” to disable the primary battery
feature or remove them if a primary battery is connected. Define the lower
limit
voltage on the primary battery using R7 and R8:
