Product Overview: MAX8808XETA+T from Maxim Integrated

The MAX8808XETA+T is a high-performance, single-cell, lithium-ion (Li+) battery charger integrated circuit (IC) designed by Maxim Integrated, a leader in analog and mixed-signal engineering. This compact and efficient IC is tailored for portable applications and is capable of operating with a USB input or an AC adapter.

Constructed with a thermally efficient TQFN package, the MAX8808XETA+T offers a precise charge voltage with a low battery leakage current, making it an ideal choice for maintaining battery charge over extended periods. It supports a charge current up to 1A, which can be programmed via an external resistor, allowing flexibility for different battery capacities.

The device features a charge cycle that begins with preconditioning, which gently ramps up the current for deeply discharged batteries. Following this, it transitions into a constant-current mode to rapidly charge the battery, and finally, it switches to a constant-voltage mode to safely top off the battery to its maximum capacity without overcharging.

The MAX8808XETA+T includes a variety of safety features to protect both the battery and the charger. These include overvoltage protection, thermal shutdown, and a timer to prevent prolonged charging. Additionally, it offers a status output that indicates charging progress and completion, which can be used to signal to a microcontroller or an LED indicator.

For design flexibility, the MAX8808XETA+T operates over a wide input voltage range and includes an automatic input selection feature that switches between USB and AC adapter power without user intervention. It's also fully compliant with USB specifications, ensuring compatibility with USB-powered devices.

In summary, the MAX8808XETA+T from Maxim Integrated is a feature-rich, reliable, and versatile charging solution for single-cell lithium-ion batteries, suitable for a wide array of portable electronic devices. Its compact size, integrated safety features, and charging efficiency make it an excellent choice for designers looking to optimize their battery management systems.
