What is LT3650EMSE-4.2#PBF used for?
The LT3650EMSE-4.2#PBF is designed for single-cell Li-Ion and LiPo battery charging in portable electronics, IoT edge devices, and solar-powered embedded systems requiring a robust, high-voltage tolerant charger IC. Its 4.2V float voltage and 2A maximum charge current suit rechargeable battery packs from 500mAh to 2Ah in wearables, handheld instruments, and remote sensor nodes. Engineers integrate this IC in battery management subsystems where input voltage sources vary widely, such as solar panels delivering 6V to 28V or unregulated wall adapters, benefiting from the LT3650's internal thermal shutdown and charge completion detection.

Frequently Asked Questions
What is the maximum charge current and float voltage of the LT3650EMSE-4.2#PBF?
The LT3650EMSE-4.2#PBF delivers up to 2A charge current with a fixed 4.2V float voltage, meeting the standard charging termination requirement for single-cell lithium-ion and lithium polymer batteries. The 4.2V float voltage ensures full charge capacity while preventing overcharge damage, and the 2A current ceiling supports charging batteries with capacities from 500mAh to over 2,000mAh within a 1C to 4C charge rate range.
What input voltage range does the LT3650EMSE-4.2#PBF support for solar and wall adapter powered charger designs?
The LT3650EMSE-4.2#PBF operates from input voltages up to 32V, making it directly compatible with unregulated wall adapters (9V to 24V), solar panels (6V to 28V open-circuit), and USB power delivery rails. This wide input voltage range eliminates the need for a pre-regulator in many designs, simplifying the BOM and reducing total charger circuit cost while maintaining a stable 4.2V charge termination for single-cell Li-Ion batteries across variable source voltages.
How does the adjustable threshold feature of the LT3650EMSE-4.2#PBF help engineers tailor the charger to different battery capacities?
The LT3650EMSE-4.2#PBF includes an adjustable charge current threshold set via an external resistor, allowing designers to program charge currents from tens of milliamps up to 2A to match the C-rate requirements of specific battery capacities. For example, a 1,000mAh LiPo cell charged at 1C requires 1A, while a 500mAh cell charged at 0.5C requires 250mA — both achievable by selecting the appropriate programming resistor value, without requiring external current sense amplifiers or complex charge controllers.
Which package does the LT3650EMSE-4.2#PBF use and how does it benefit compact portable device charger PCBs?
The LT3650EMSE-4.2#PBF is housed in a 12-lead MSOP (Mini Small Outline Package) with a plastic/epoxy body, offering a smaller footprint than standard SOIC-8 or DIP packages while maintaining ease of hand soldering for prototyping. The MSOP package measures approximately 3mm x 5mm, allowing the full Li-Ion charger circuit including programming resistors to fit within a 10mm x 15mm PCB area — ideal for wearables, handheld devices, and IoT sensor nodes with tight spatial constraints requiring a 4.2V, 2A charging solution.
