DESCRIPTIO
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...
