LTC4065AEDC#TRMPBF - Linear Technology

The LTC4065AEDC#TRMPBF is a compact, high-efficiency, USB-compatible single-cell lithium-ion battery charger designed and manufactured by Linear Technology. This advanced charging solution is engineered to provide a reliable and convenient method for charging 4.2V lithium-ion cells, which are commonly used in portable electronic devices.

With its small footprint, the LTC4065AEDC#TRMPBF is an ideal choice for space-constrained applications. It comes in a low-profile (0.75mm) 6-pin 2mm x 2mm DFN package, which is suitable for modern, compact electronic assemblies. The charger's integrated thermal regulation prevents overheating, ensuring safe operation and extending the lifespan of both the charger and the battery.

The device offers a programmable charge current up to 950mA via a single external resistor. This feature allows designers to customize the charge rate for various battery capacities and sizes, optimizing the charging process for specific application requirements. Additionally, the LTC4065AEDC#TRMPBF includes an internal MOSFET and current sense resistor, which simplifies the design and reduces external component count.

Another key feature of this product is its automatic recharge capability. The charger initiates a new charging cycle if the battery voltage falls below an internal threshold, ensuring the battery remains fully charged over time. The LTC4065AEDC#TRMPBF also boasts a charge current monitor, allowing for real-time observation of the charging process.

Protection features are paramount in battery charging applications, and the LTC4065AEDC#TRMPBF does not fall short. It includes undervoltage lockout, automatic recharge, and thermal regulation to safeguard both the battery and the charger. Furthermore, the device is designed to suspend charging if the input voltage falls below a programmed level, preventing damage to the battery and ensuring efficient operation.

This product is ideal for a wide range of portable electronic devices, including digital cameras, MP3 players, Bluetooth headsets, and handheld medical and industrial devices. Its performance, coupled with Linear Technology's reputation for high-quality power management solutions, makes the LTC4065AEDC#TRMPBF a top-tier choice for designers and manufacturers looking to integrate a reliable charging solution into their products.
