LT3650EMSE in Linear Tech / ADI LT Series Family
The LT3650EMSE is a family of monolithic power tracking battery chargers produced by Analog Devices (Linear Technology) designed for single or dual-cell Lithium-Ion and Lithium-Polymer packs. Operating over a wide input voltage range up to 32V, these buck-regulator based ICs provide a constant-current/constant-voltage charge characteristic with a programmable maximum charge current up to 2A. The family is specifically engineered for efficient power management in compact form factors requiring minimal external components and precise termination control.
Variants in This Sub-Family
Variants within the LT3650EMSE sub-family primarily differ based on their preset float voltages, such as 4.1V, 4.2V, 8.2V, or 8.4V, to accommodate specific Li-ion chemistries and cell configurations. Some versions also differ in their termination logic, offering either a fixed C/10 termination or a user-programmable safety timer, allowing designers to optimize for fast charging or maximum battery longevity.
