Description

The LTC4002EDD from Linear Technology is a robust and highly efficient standalone linear battery charger designed for single-cell lithium-ion batteries. This compact device is housed in a small 10-pin DFN package, making it an ideal solution for space-constrained applications.

With an input voltage range of 4.5V to 10V, the LTC4002EDD can accommodate a variety of power sources, including wall adapters and USB ports. Its adjustable charge current capability allows for up to 2A of charge current, providing the flexibility needed to cater to different battery capacities and charging speed requirements.

One of the key features of the LTC4002EDD is its automatic recharge feature. The charger initiates a new charging cycle if the battery voltage falls below a preset threshold, ensuring that the battery remains fully charged without the need for manual intervention. Additionally, the device incorporates a charge current monitor, which allows for accurate measurement of the charge current, enabling the user to monitor the charging process effectively.

The LTC4002EDD also boasts a number of safety features to protect both the battery and the charger. These include overvoltage protection, which prevents the battery from being overcharged, and thermal regulation, which reduces charge current if the internal temperature of the device exceeds a safe threshold. Furthermore, the charger has a shutdown mode that reduces the supply current to 15µA, significantly conserving battery life when not in active use.

For status indication, the LTC4002EDD provides a charge status output pin. This allows for an external LED or other indicator to show the charging progress, giving users a clear visual indication of the charging state. The precision end-of-charge control ensures that the battery is charged to its full capacity safely and efficiently.

In summary, the LTC4002EDD from Linear Technology is a versatile and reliable charging solution, perfect for portable electronics requiring efficient and safe battery management. Its compact size, combined with powerful features, makes it an excellent choice for designers looking to optimize their power management systems.
