Product Overview: LTC4065LXEDC#TRPBF

The LTC4065LXEDC#TRPBF is a highly integrated and efficient linear battery charger from Linear Technology, designed to charge single-cell lithium-ion batteries. This compact and reliable solution is ideal for portable applications where space and power efficiency are critical. The LTC4065LXEDC#TRPBF comes in a small, low-profile (2mm x 2mm) DFN package, making it an excellent choice for space-constrained devices such as wearables, medical devices, and wireless sensors.

Key Features:

• Advanced Charging Algorithm: The product incorporates a constant-current/constant-voltage charging algorithm with programmable charge current up to 950mA, ensuring fast and efficient charging of the battery while maximizing its lifespan.
• Thermal Regulation: To protect the battery and circuitry from overheating, the LTC4065LXEDC#TRPBF features an internal thermal regulation mechanism that automatically reduces charge current under high temperature conditions.
• Automatic Recharge: The charger includes an automatic recharge feature that initiates a new charging cycle when the battery voltage falls below a preset threshold, keeping the battery topped up and ready for use.
• Charge Status Indication: An onboard charge status output pin can be used to drive an LED or interface with a microcontroller, providing visual or digital indication of the charging process.
• Low Profile: The DFN package is not only small in footprint but also in height, enabling integration into ultra-thin applications.

Protection Features:

• Overvoltage Protection: The device offers protection against input overvoltage, which can occur during faulty power supply conditions, ensuring the safety of the charging system.
• Undervoltage Lockout: It also includes an undervoltage lockout (UVLO) feature that disables the charger when the input voltage falls below a certain threshold to prevent system instability or damage.
• No Battery Drain: When the input supply is removed, the LTC4065LXEDC#TRPBF has a near-zero current draw from the battery, preserving charge during periods of inactivity or storage.

The LTC4065LXEDC#TRPBF is a testament to Linear Technology's commitment to providing advanced power management solutions. Its combination of compactness, efficiency, and safety features makes it an excellent choice for designers looking to incorporate a reliable charging solution into their next battery-powered project.
