Frequently Asked Questions
What charge current and float voltage does LT3650IDD-4.1 deliver for single-cell Li-ion batteries?
The LT3650IDD-4.1 provides up to 2 A programmable charge current with a precisely regulated 4.1 V float voltage having ±0.5% accuracy. This combination supports standard single-cell Li-ion batteries in portable devices, ensuring full charge capacity without overvoltage risk.
How does the LT3650IDD-4.1 handle thermal protection during high-current charging?
LT3650IDD-4.1 includes a thermistor input that monitors battery temperature and reduces or suspends charging outside safe limits, typically below 0°C or above 45°C. This safety feature prevents damage to Li-ion cells during 2 A charging in environments with elevated ambient temperatures up to 125°C.
Which solar-charging designs benefit from LT3650IDD-4.1 operating from inputs up to 32 V?
Remote IoT nodes, wildlife monitoring stations, and solar-powered GPS trackers that harvest energy from panels producing up to 32 V can directly feed LT3650IDD-4.1 to charge a single Li-ion cell at 2 A. The wide input range eliminates the need for a pre-regulator stage, simplifying the power path to a single 12-pin DFN IC.
When should LT3650IDD-4.1 be chosen over a switching-mode Li-ion charger for a portable design?
LT3650IDD-4.1 is the better choice when EMI-sensitive applications like medical or audio equipment require a noise-free linear charger architecture, and when the input-to-output voltage differential is small enough to keep the 2 A linear charger power dissipation within the 12-pin DFN thermal limits, typically below 2 W total.
