Linear Technology LTC4059EDC: A Compact, Efficient Charging Solution

The LTC4059EDC by Linear Technology is a highly integrated linear charger designed for single-cell lithium-ion batteries. This compact and efficient charging solution is specifically tailored for portable applications where space is at a premium. Its small form factor is facilitated by the 2mm x 2mm DFN package, making it an ideal choice for modern, space-constrained devices.

Key Features

• Adjustable Charging Current: The LTC4059EDC offers an adjustable charge current up to 750mA, allowing for flexibility in charging different battery capacities. This ensures that the charging process is optimized for each specific battery, enhancing both the performance and longevity of the device's power source.
• Integrated Thermal Regulation: To maintain safety and reliability, the LTC4059EDC includes an integrated thermal regulation feature that prevents overheating by reducing charge current during high temperature conditions. This is essential for maintaining the integrity of the battery and preventing damage to the device.
• Automatic Recharge: Once the charging process is complete, the LTC4059EDC automatically initiates a recharge cycle when the battery voltage falls below a preset threshold. This ensures that the battery remains fully charged without the need for manual intervention.
• No External MOSFET, Sense Resistor, or Blocking Diode Required: The LTC4059EDC's design eliminates the need for external components such as a MOSFET, sense resistor, or blocking diode, which simplifies the design and reduces the overall footprint of the charging circuit.

Applications

The LTC4059EDC is particularly suited for a wide range of portable electronic devices, including:

• Handheld Instruments
• Bluetooth Devices
• Portable Medical Equipment
• Wearable Technology
• Wireless Headsets

With its advanced features and compact size, the LTC4059EDC from Linear Technology represents a smart, space-saving charging solution that delivers both performance and convenience for designers and end-users alike.
