LTC4064
Monolithic Linear Charger
for Back-Up Li-Ion Batteries
U FEATURES DESCRIPTIO в–  The LTC4064 is a standalone linear charger optimized for
prolonging the life of 1-cell Li-ion batteries in battery backup applications. By charging to a float voltage of 4V
instead of 4.2V or 4.1V, the LTC4064 decelerates the aging
process and capacity degradation when the battery is
unused for long periods of time but must be in a ready
state. в–
