Description:

Li-ion/polymer shunt battery charger.

LTC4070, Li-Ion/Polymer Shunt Battery Charger

The LTC®4070 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

LTC4070 Features

* n Low Operating Current (450nA) n 1% Float Voltage Accuracy Over Full Temperature and Shunt Current Range n 50mA Maximum Internal Shunt Current (500mA with External PFET) n Pin Selectable Float Voltage Options: 4.0V, 4.1V, 4.2V n Ultralow Power Pulsed NTC Float Conditioning for Li-Ion/Polymer P
