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
