e-peas AEM00900 Harvesting Sources Battery Charger

e-peas AEM00900 Harvesting Sources Battery Charger is a low-cost compact PMIC with source voltage level configuration for pulsed energy sources or constant voltage PV. This battery charger is an integrated energy management circuit that extracts energy from several energy harvesting sources and stores it in a storage element. The AEM00900 battery charger operates at 120mV to 1.5V input and 2.8V to 4.8V output voltage range and 250mV at 5µW input power (typical) cold start. This harvesting source battery charger comes in a QFN28 4mm x 4mm package. Typical applications include wall switches, remote controls, detectors, and door/window openings in smart homes or buildings.

Features

-40°C to 125°C operating junction temperature range
Cold start from 250mV input voltage and 5µW input power (typical):
- Fast start-up from source
0.12V to 1.47V constant input voltage regulation:
- Optimized for single/dual elements capacitive PV cell, intermittent and pulsed power sources
Selectable over-discharge and overcharge protection:
- Supports various types of rechargeable batteries (LiC, Li-ion, LiPo, super-capacitor, and Li-ceramic pouch)
Ultra-low power idle modes:
- Stored energy is preserved when no source is available
Shipping and shelf mode:
- Prevents energy drain from the battery when no source is available (KEEP_ALIVE pin)
- Disables storage element charging (DIS_STO_CH pin)
