AEM13920
Dual input energy harvesting
FEATURES
Dual sources inputs:
- Optimized boost operation for each source
- Efficiency above 90% on each source
- Harvests from 110 mV / 2 μW after cold start
- Simultaneous harvesting from both sources
MPPT and constant voltage modes:
- Both modes are available for both sources to ensure optimal harvesting from multiple combinations of harvesters (PV cells, RF, vibration, pulsed sources…)
Cold start from 275 mV / 5 μW input
- Startup at ultra-low power from either harvesting source input
Selectable overdischarge and overcharge protection:
- Supports various types of rechargeable batteries (LiC, Li-ion, LiPo, Li-ceramic pouch…)
Regulated output for application circuit:
- Buck regulator with efficiency above 90%
- Selectable output voltage between 0.6 V and 2.5 V
- Output current up to 100mA
Thermal monitoring:
- Battery protection against over-tempreture and under-tempreture during charging and discharging, independently
Power meter:
- Measures how much energy has been transferred to the battery by each source and the energy drained from the battery to supply the application circuit
System configuration by GPIO or I2C communication
- All settings are dynamically configurable through GPIO or I2C (Fast Mode Plus)
- System data is available through I2C
Shipping mode
- Disables charging and discharging battery during shipment
External 5 V charging capability
- Extra charging input for 5 V power supplies
- CC/CV charging with configurable current limit in CC mode (max. 135 mA)
- Provides a fast charging alternative when no source is available for a long time
