Ultra Low Voltage Boost Power Management IC for Solar and Thermal Energy Harvesting MB39C831 Ultra Low Voltage Boost PMIC, Maximum Power Point Tracking MB39C831 is a high efficiency, synchronous rectification boost DC/DC converter that can charge a Li-ion battery with a single solar cell and a multi-junction solar cell or Thermal Electric Generator(TEG). The DC/DC convertor can extract the maximum power point (MPP) of the power source and safely charges into Li-ion battery with the protection function. MB39C831 can start up from 0.35V also and operates at very low voltage. As such it is suitable for various applications driving from a single solar cell. feature · Input Voltage Range: 0.30V to 4.75V · Lowest Start-Up Voltage: 0.35V · Selectable Output Voltages: 3.0V, 3.3V, 3.6V, 4.1V, 4.5V, 5.0V · Quiescent Current (Constant Voltage Mode) : 32uA(No Load) · Input Peak Current Limit: 200mA · Maximum Power Point Tracking (MPPT) · Over Voltage/ Current Protection for Charger · Power-Save Mode: · QFN40: 6.0mm μ 6.0mm μ 0.85mm (Pin pitch 0.5mm) Item Conditions Min Typ Max Unit Input Start-Up Voltage VDD(Ta=25°C) — 0.35 0.50 V VDD Input Voltage VDD 0.3 — 4.75 V Output Voltage Select MPPT_ENA=L S[2:0]=0h-5h 3.0 — 5.0 V Battery Charging Mode — 41 82 uA Constant Voltage Mode — 32 64 uA -40 — +85 °C Quiescent Current Operating Ambient Temperature Ta Note: Green IT Award is an Japanese Prize. block diagram · Thermal Electric Generator(TEG) · Photovoltanic Cell CIN CIN VDD VST VDD LX VST STARTUP VCC CSH0 DC/DC MPPT FB MPPT_IN ENA MPPT_OUT MPPT_ENA PGND VOUT FB CSH2 Li-ion Battery MPPT_IN ENA S0,S1,S2 Power source : Power generator from solar-cells COUT Li-ion Battery MPPT_OUT MPPT_ENA DET1 CVCC VOUT_S CSH1 COUT DET0 GND DC/DC MPPT CSH0 VOUT CSH2 S0,S1,S2 VCC CVCC VOUT_S CSH1 LX STARTUP DET0 GND PGND DET1 Power source : Power generator from Thermal Electric Generator system diagram Energy Source Power Generation Device Light Vibration Thermal Radio Wave Solar Cells Peltier Electromagnetic Induction PMIC Sensing & CPU RF MB39C831 (Boost) Sensor MCU Memory ZigBee GP Bluetooth LE 2.4GHz, 920MHz Cloud Power Generation Part application or Network of Mobile Tablet PC Control & Wireless Part starter kit Sensor · Solar Energy Harvesting LCD Memory · Thermal Energy Harvesting · Cell Phone · eBook · Electronic Dictionary · Wireless Sensor Node MB39C831 web design simulation service URL: http://www.spansion.com/easydesignsim/ Contact Us: Nomura Shin-Yokohama Building, 2-10-23 Shin-Yokohama, Kohoku-Ku, Yokohama, Kanagawa, 222-0033, Japan | +81 45 473 6550 Spansion: 915 DeGuigne Drive, PO Box 3453, Sunnyvale, CA 94088-3453 USA www.spansion.com ©2013 Spansion®, the Spansion logo, MirrorBit®, MirrorBit® Eclipse™ and combinations thereof, are trademarks and registered trademarks of Spansion LLC in the United States and other countries.
