E-PEAS AEM20940 THERMAL ENERGY HARVESTING

Product Overview

Highly-efficient, regulated dual-outputs, ambient energy manager for TEG with optional primary battery

Product Features:

Ultra-low-power start-up:
– Cold start from 60 mV input voltage and 150µW input power with the optional external module (typical)
– Cold start from 380 mV and 100 µW input power without the optional external module (typical)

Ultra-low-power boost regulator:
– Open-circuit voltage sensing for MPPT every 21s
– Configurable MPPT with 2-pin programming
– Selectable Voc ratios of 50, 55 or 75 %
– Input voltage operation range from 50 mV to 5V
– MPPT voltage operation range from 50 mV to 5V
– Constant impedance matching (ZMPPT)

Integrated 1.2/1.8 V LDO regulator:
– Up to 20 mA load current
– Power gated dynamically by external control
– Selectable output voltage

Integrated 1.8/2.5/3.3 V LDO regulator:
– Up to 80 mA load current with 300 mV drop-out
– Power gated dynamically by external control
– Selectable output voltage

Flexible energy storage management:
– Selectable overcharge and overdischarge protection for any type of rechargeable battery or (super)capacitor
– Fast supercapacitor charging
– Warns the load when battery is running low
– Warns when output voltage regulators are available

Optional primary battery:
– Automatically switches to the primary battery when the secondary battery is exhausted
Integrated balun for dual-cell supercapacitor
