Charging circuit composed of LTC4064

Relevant key device information applied in this article: LTC4064 The LTC4064 independent charger produced by Linear Technology is optimized and designed to extend the service life of lithium-ion batteries. It only charges lithium-ion batteries to 4.0V (instead of 4.1V or 4.2V) float voltage. The LTC4064 slows the aging process of lithium-ion batteries and capacity degradation caused by low usage of lithium-ion batteries (but must remain fully charged for long periods of time).
