Description

LTC4402-1EMS8#TRPBF - Battery Charger from Linear Technology

The LTC4402-1EMS8#TRPBF is a high-efficiency, constant-current/constant-voltage linear charger specifically designed by Linear Technology for charging single-cell lithium-ion batteries. Its small package and low external component count make it an ideal choice for portable applications where space and weight are critical considerations.

This advanced charging IC is housed in an MSOP-8 package and is part of the LTC4402 series, known for its reliable and efficient battery management solutions. The LTC4402-1EMS8#TRPBF offers a programmable charge current up to 800mA, which can be set by a single external resistor. This flexibility allows it to accommodate a wide range of battery sizes and desired charge rates.

One of the key features of this product is its ability to operate with very low dropout voltage. This characteristic ensures that charging can continue even when the input supply voltage is only slightly higher than the battery voltage, making the most of available power and extending battery life in the process.

The LTC4402-1EMS8#TRPBF also includes a variety of safety features to protect both the battery and the charger during operation. These features include automatic recharge, thermal regulation to prevent overheating, and a timer to terminate charge after a predetermined interval. Additionally, the device has an under-voltage lockout (UVLO) feature that ensures the charger operates only when the input voltage is within an acceptable range.

For status indication, the LTC4402-1EMS8#TRPBF provides a charge status output that can be used to drive an external LED, offering a visual cue for the charging process. This can be particularly useful in handheld devices where user feedback is essential.

Overall, the LTC4402-1EMS8#TRPBF is a robust and versatile charging solution that delivers performance, safety, and convenience in a compact form factor. It's an excellent choice for designers looking to incorporate a reliable battery charging system into their next portable device project.
