e-peas AEM10941 EVK Evaluation Kit
FEATURES
Connectors
- 1 screw connector for the photovoltaic cell
- 1 screw connector for the storage element
- 1 screw connector for primary battery
- 1 screw connector for HVOUT LDO output (80mA @ 1.8 – 4.1 V)
- 1 screw connector for LVOUT LDO output (20mA @ 1.2 or 1.8 V)
Configuration
- 2 headers SELMPP[1:0] to define the MPPT ratio linked to the harvester technology
- 3 headers CFG[2:0] to define the storage element protection levels
- 6 resistors footprint related to the custom mode (CFG[2:0] = LLL)
- 2 headers to enable/disable the internal LDOs
- 2 headers to disable the primary battery feature
- 1 headers to set the dual cell supercapacitor BAL feature
Size
- 76mm x 49mm
- 4 x M2.5 Mounting holes
SUPPORT PCB
BOM around the AEM10941
Footprint & Symbol: Available in the datasheet
STEP 2: Connect the storage element (and the primary battery)
STEP 3 : Connect the load(s) to HVOUT / LVOUT
STEP 4: Connect the harvester
Internal Boost efficiency Vs. input voltage (LBOOST = 22 μH)
STEP 5: Check the status
Status pins
STATUS[2]| 19| Logic output. Asserted when the AEM performs a MPP evaluation.
STATUS[1]| 20| Logic output. Asserted during 600 ms if the battery voltage
falls below Vovdis or asserted as long as the AEM is taking energy from the
primary battery.
STATUS[0]| 21| Logic output. Asserted when the LDOs can be enabled.
