Product Overview: LT3650EMSE-8.4#TRPBF

The LT3650EMSE-8.4#TRPBF is a highly efficient, single-cell lithium-ion/polymer battery charger produced by Analog Devices Inc., a leader in the design and manufacturing of high-performance analog integrated circuits. This advanced charging IC is designed to cater to a wide variety of applications including portable electronics, industrial, automotive, and medical devices.

The LT3650EMSE-8.4#TRPBF offers a charging voltage fixed at 8.4 volts, making it suitable for charging 2-cell lithium batteries. It features a programmable charge current up to 2A, which allows for fast charging capabilities while maintaining precision and safety. The device operates over a wide input voltage range from 4.95V to 32V, providing flexibility in various power environments and ensuring compatibility with a range of power sources.

This product integrates several notable features that enhance its performance and reliability. It includes an automatic recharge feature, which initiates a new charging cycle if the battery voltage falls below a preset threshold, ensuring the battery remains fully charged. Additionally, the IC has an onboard thermal regulation mechanism that protects the device by reducing charge current in the event of excessive temperature rise.

Safety is a paramount concern in battery charging, and the LT3650EMSE-8.4#TRPBF addresses this with its multiple safety features. It has built-in charge termination based on the C/10 principle, where charging is terminated when the charge current falls to one-tenth of the programmed maximum. Furthermore, it provides an optional timer termination to top off the charge cycle, as well as NTC temperature sensing to prevent charging if the battery temperature is outside a specified range.

The device comes in a compact, 12-pin MSOP package with an exposed pad to facilitate heat dissipation. It is also RoHS compliant and lead-free, adhering to environmental standards and regulations. The “TRPBF” suffix denotes that the product is provided in tape and reel packaging, which is suitable for automated assembly processes, making it ideal for high-volume production needs.

In summary, the LT3650EMSE-8.4#TRPBF from Analog Devices Inc. is a sophisticated, versatile, and reliable choice for designers looking to implement an efficient charging solution for 2-cell lithium-ion/polymer batteries in their applications.
