LTC4070EMS8E#PBF, Battery Charger IC, Li-Ion/Li-Pol, 3.1 V Input, 4/4.1/4.2 V/50 mA Charge, -40 to 125 °C, MSOP-EP-8

Semiconductors - ICs\Power Management ICs - PMIC\Battery Management\Battery Charger ICs LTC4070 is a Li-Ion/polymer shunt battery charger system. It allows simple charging of Li-Ion/Polymer batteries from very low current, intermittent or continuous charging sources. The 450nA to 50mA operating current makes charging possible from previously unusable sources. With the addition of an external pass device, shunt current may be boosted to 500mA. Stacked cell high voltage battery packs are inherently balanced with shunt charging. With its low operating current, this device is well suited to charge thin film batteries in energy harvesting applications where charging sources may be intermittent or very low power. The unique architecture of the device allows for an extremely simple battery charger solution; requiring just one external resistor. It is used in application such as low power Li-Ion/Polymer battery back-up, solar power systems with back-up, memory back-up, embedded automotive, thin film batteries, energy scavenging/harvesting etc. • 1% float voltage accuracy over full temperature and shunt current range • Ultralow power pulsed NTC float conditioning for Li-Ion/Polymer protection • Low and high battery status outputs • Simple low voltage load disconnect application • Programmable float voltage is 4V typical at (VADJ = 0V, VNTC = VCC, TA = 25°C) • Operating temperature is -40°C to 125°C • Package style is 8-lead plastic MSOP
