The LT3652’s key market differentiators and attributes include: a solar power supply voltage regulation loop for maximum peak power tracking (MPPT) in solar applications; a wide input voltage range of 4.95V to 32V (with a 40V absolute maximum rating); a resistor programmable float voltage of up to 14.4V that accommodates Li-Ion/Polymer, LiFePO4, SLA Chemistries; user-selectable charge termination at a charge current of one tenth of the programmed maximum (C/10) or with an onboard termination timer; and a current draw of less than 1µA from the battery during non-charging periods, saving battery run time.
