TYPICAL APPLICATION
Li-Ion/Polymer Shunt
Battery Charger System with
Low Battery Disconnect
DESCRIPTION
The LTC ? 4071 allows simple charging of Li-Ion/Polymer
batteries from very low current, intermittent or continuous
charging sources. A near-zero current low battery latch-
ing disconnect function protects even the lowest capacity
batteries from deep discharge and potentially irreparable
damage. The 550nA to 50mA operating current makes
charging possible from previously unusable sources. With
its low operating current the LTC4071 is well suited to
charge low capacity Li-Ion or thin film batteries in energy
harvesting applications. The unique architecture of the
LTC4071 allows for an extremely simple battery charger
solution, requiring just one external resistor.
The LTC4071 offers a pin selectable float voltage with ±1%
accuracy. The integrated thermal battery qualifier extends
battery lifetime and improves reliability by automatically
reducing the battery float voltage at NTC thermistor tem-
peratures above 40°C. The LTC4071 also provides two
pin selectable low battery disconnect levels and a high
battery status output.
The device is offered in two thermally enhanced packages,
a compact low profile (0.75mm) 8-lead (2mm × 3mm)
DFN and an 8-lead MSOP package.
