LTC4054ES5-4.2 Batteria Caricabatteria SOT23-5

The LTC4054ES5-4.2 is a complete constant-current/constant-voltage linear charger for single-cell lithium-ion batteries. Housed in a tiny SOT23-5 package, this standalone charger IC is ideal for portable applications. It requires few external components and is well-suited for space-constrained applications. The LTC4054ES5-4.2 employs a thermal feedback regulation loop to protect the IC from excessive temperature during high power operation or high ambient temperature. This feature maximizes the charging rate without the risk of damaging the IC.

This battery charger IC is designed to work with a single lithium-ion cell and provides a fixed charge voltage of 4.2V, which is the standard voltage for most lithium-ion batteries. The external resistor programs the charge current. The charge current can be programmed up to 800mA. The LTC4054ES5-4.2 automatically terminates the charge cycle when the charge current drops to 1/10th of the programmed value after the final float voltage is reached. This feature ensures that the battery is fully charged without overcharging, which can damage the battery and reduce its lifespan.

The SOT23-5 package is a small, surface-mount package that is ideal for portable applications. The small size of the package allows the LTC4054ES5-4.2 to be used in a wide range of applications, including MP3 players, Bluetooth headsets, and other portable devices. The LTC4054ES5-4.2 also includes a built-in reverse blocking diode, which prevents current from flowing back into the charger from the battery. This feature protects the charger from damage if the battery is accidentally connected in reverse polarity.

The LTC4054ES5-4.2 is easy to use and requires few external components. The charge current is programmed by a single external resistor, and the charge cycle is automatically terminated when the battery is fully charged. The LTC4054ES5-4.2 also includes a status pin that can be used to indicate the charge status of the battery. This pin can be connected to an LED or other indicator to provide visual feedback to the user.

In summary, the LTC4054ES5-4.2 Batteria Caricabatteria SOT23-5 is a compact, efficient, and easy-to-use linear charger for single-cell lithium-ion batteries. Its small size, thermal feedback regulation, and automatic termination make it an ideal choice for portable applications.
