Analog Devices Inc. LTC4065EDC-4.4#TRMPBF

The LTC4065EDC-4.4#TRMPBF is a highly integrated and compact standalone linear battery charger from Analog Devices Inc., designed specifically for charging single-cell lithium-ion batteries. This advanced charging solution is housed in a small, low-profile 6-pin DFN package, making it an ideal choice for portable applications where space is at a premium.

With an input voltage range of 4.25V to 6.5V, the LTC4065EDC-4.4#TRMPBF is versatile and can accommodate a variety of power sources, including USB ports and wall adapters. The charger is optimized for use with batteries that require a final float voltage of 4.4V, and it can deliver up to 950mA of continuous charge current, which is thermally limited and adjustable via an external resistor.

One of the key features of this product is its automatic recharge capability. The charger initiates a new charging cycle if the battery voltage falls below a preset threshold, ensuring that the battery remains fully charged. Additionally, the LTC4065EDC-4.4#TRMPBF incorporates an internal thermal feedback mechanism that regulates the charge current to limit the temperature rise during operation, enhancing the safety and longevity of both the charger and the battery.

Safety is a top priority, and the LTC4065EDC-4.4#TRMPBF includes multiple protection features. Overvoltage protection shields the battery from input voltage spikes, and the charger automatically shuts down if the input voltage exceeds a specified limit. Furthermore, the device features a charge current monitor output for charge current monitoring or for termination, and a C/10 charge termination indicator output.

The LTC4065EDC-4.4#TRMPBF is also designed for ease of use, with a minimal external component count. This not only simplifies the design and reduces the overall solution footprint but also helps accelerate the time-to-market for end products.

Overall, the LTC4065EDC-4.4#TRMPBF from Analog Devices Inc. is a reliable, efficient, and space-saving charging solution that offers advanced features for single-cell lithium-ion battery charging applications in portable electronics.
